knowing the processes that have shaped the geography"

NATURAL
RESOURCES
Artist George Catlin, traveling by steamboat up the Missouri River in 1832, went ashore to climb a steep prairie-covered bluff and discovered a landscape where, as he wrote, "…thousand velvet-covered hills go tossing and leaping down with steep or graceful declivities" (Mutel 1989a). He was describing the Loess Hills: a narrow north-south band of rugged hills stretching along the eastern edge of the pancake-flat Missouri River floodplain in present-day Iowa. These "mountains in miniature" (as they were later called) could not fail to draw the attention of early explorers.
Topography
The Loess Hills are a distinctive topographic region encompassing over 640,000 acres and extending for nearly 200 miles in a narrow band adjacent to the Missouri River valley. They constitute one of seven principal landform regions in Iowa (Figure 2). Although loess is a widespread geologic deposit, its development in western Iowa is of such magnitude, accumulating to depths of 150 feet in
some places, that it dominates the
landscape. The terrain is characterized by distinctive shapes: steep, narrow ridge crests, peaks, and saddles; numerous steep side slopes and branching spurs; and precipitous bluffs, some with sheer, nearly vertical faces rising from the adjoining Missouri River floodplain. These deposits form an extensive landscape of unique hill forms that are unparalleled in the United States and rare around the world. The Loess Hills' intricately sculptured loess deposits
have been described as "the best example of loess topography not only in the Central Lowlands, but in the United States." (NPS 1985). This striking landform is an outstanding example of a landscape formed by two fundamental geological processes -- wind and erosion.
Geology
Loess is a common geologic material and is thinly spread over much of the country's agricultural midsection. More significant accumulations of this windblown silt are known especially from eastern Washington State, southeastern Nebraska, the central and southern Mississippi Valley, as well as the Midwest. It is, however, the large contiguous tracts of unusually thick loess sculpted into a distinctive topography with a significant geologic record that sets the Loess Hills of western Iowa apart from the others.

A SENSE OF
PLACE: THE HUMAN STORY
"When I am here, the
spirits of our ancestors are all around me"
-Pete Fee, Ioway Tribe Iowa-Portrait of the Land (2000)
The human story of the Loess Hills of western Iowa is integrally related to
the tale of the landform region's prehistoric and historic occupants over the
last 12,000 to 13,000 years. American Indians have lived in, hunted in, farmed
in, and traveled throughout the landform region for thousands of years. In the
historic period, the Loess Hills were home to tribes that were indigenous to
the region, such as the Ioway (Iowa) and Otos; they were also home to the
displaced Potawatomis. French fur traders and missionaries discovered the Loess
Hills in the early 1700s. Several historically important routes crossed through
and paralleled the Loess Hills, including the paths taken by Lewis and Clark in
1804 and the Mormons from 1846-1869. A "track" of the Underground
Railroad led slaves from Kansas to freedom by way of the Loess Hills of Fremont
County. Determined farmers employed whatever technology was available to raise
crops on the steep hillsides. This human story is woven into the fabric of the
Loess Hills.
A brief sketch highlighting human use and occupation of the Loess Hills
follows. For a detailed report on the prehistory and history of the study area,
see Appendix C.
American Indian Occupation
Present knowledge of Loess Hills archeology hints at special
relationships between humans and Loess Hills resources at different times in
the past. The steep and narrow valleys in the Loess Hills may have offered
shelter from the elements, at least on a seasonal basis, and thus been a
preferred place of seasonal residence. Small valleys within the Hills may have
offered both timber and arable land needed for small farming communities to
prosper in Late Prehistoric times. One locality, near Glenwood, appears to have
especially attracted farming people, whose lodges and fields dotted the
prehistoric landscape there for perhaps 250 years or more. The sweeping vistas
of the Missouri River valley afforded by the high bluffs and ridges of the
Loess Hills may have been a factor in choosing suitable eternal resting places
for the dead. The reasons for these apparent relationships may be better
understood in the future as our knowledge of the archeological record of the
Loess Hills increases. The Loess Hills may be viewed as a storehouse of
knowledge that is "banked" for the future.
Paleoindian Period: As
glaciers receded in the upper Midwest, winds accumulated fine quartz silt into
thick loess deposits in western Iowa. Humans arrived soon after most of the
sediment was deposited, about 11,000 B.C. to 8,500 B.C. These Paleoindians were
small bands of foragers who led a nomadic existence, roaming the hills and
plains in search of large game herds, such as bison, mammoths, and mastodons
(Benchley et al. 1997; Alex 2000). These people are characterized in the
archeological record by the highly distinctive, finely crafted, chipped stone
projectile points that they fashioned to serve as spear tips and hand cutting
tools. In the Loess Hills, Paleoindian projectile points have been found as
isolated artifacts in several locations, but no habitation or game
kill/processing sites are known. Although evidence of the Paleoindian period in
the Loess Hills is scant, future discoveries of Paleoindian artifacts,
associated with the remains of large game animals hunted during Paleoindian
times, is a strong possibility.
Archaic Period: The next
archeological period represented in the Loess Hills is the Archaic (8,500 B.C.
to approximately 800 B.C.). Archaic sites, recognized by notched and stemmed
projectile points, have been documented in the study area. Although still
highly mobile, Archaic peoples made greater use of semi-permanent base camps as
well as smaller seasonal camps. Throughout the approximately 8,000-year span of
the Archaic period, small mobile groups, probably based on nuclear or extended
families, engaged in hunting and gathering as primary economic pursuits.
However, through time, as the resources exploited became more diversified,
groups became less mobile. Greater use was made of seasonal resource
exploitation base camps and band composition became larger and more cohesive.
People came together repeatedly to bury their dead in given localities and with
more variety of burial artifact accompaniments. These changes were gradual and
are difficult to perceive in the archeological record because Archaic-age
archeological sites are few and generally little investigated, particularly in
the Loess Hills. The eventual transition to what archeologists call the
Woodland period is marked not so much by changes in lifestyle as by the
introduction or elaboration of new ways of obtaining food and burying the dead.
Woodland Period: The Archaic period was succeeded by the Woodland
(approximately 800 B.C. to A.D. 1200) and is characterized by the introduction
of ceramic vessels, burial of the dead in mounds, and increased reliance on
wild and cultivated plant foods. Regional differences in artifact assemblages,
particularly the decoration of pottery, became more distinct through the
Woodland period. Woodland period people were more sedentary than their
predecessors were, as exemplified by the small hamlets of substantial
wattle-and-daub or earth-covered structures that they lived in. Like the
Archaic period, the Woodland period is divided into Early, Middle, and Late
subperiods. The regional Woodland variation found in western Iowa, including
the Loess Hills, is often termed Plains Woodland or sometimes the Mid-America
Woodland tradition (Benchley et al. 1997; Benn 1986). Woodland sites are
generally more abundant than Archaic sites.
The Late Prehistoric Period: By the advent of the Late
Prehistoric period (A.D. 900-1000 through approximately A.D. 1650), changes
transformed Late Woodland cultures into several strikingly different regional
archeological complexes that were centered on a settled village life and based
largely on the raising of garden crops. Widespread cultivation of corn on an
intensive scale led to the development of several distinctive regional cultures
whose people lived in permanent settlements and whose economy was based on a
blend of corn cultivation and hunting. These included three distinctive village
complexes that flourished in the Loess Hills. All three (Great Oasis, Mill
Creek, and Nebraska Phase) were approximately coexistent, and their presence in
the Loess Hills lasted about 300 years. With the possible exception of Great
Oasis, who may not have raised much corn, but may have obtained it from Mill
Creek neighbors, these complexes shared a basic economy that consisted of
horticulture and seasonal hunting of bison and other mammals, supplemented by
the gathering of wild plant foods, mussels, and fish. The Nebraska Phase people,
like their Mill Creek and Great Oasis neighbors in the northern Loess Hills,
disappeared from the archeological record in Iowa by about A.D. 1300 (Alex
2000).
Early Euro-American Contact
and Settlement
Whatever unknown circumstances caused the elimination of Late
Prehistoric peoples from the Loess Hills in the 14th century, the
effect was lasting. For more than three centuries, the Loess Hills were
virtually devoid of human activity. Evidence indicates that by the mid-17th
century, occasional use of the Loess Hills by native people, now in contact
with the earlyFrench fur traders, had recurred.
The French trader LeSeuer heralded the beginning of the historic period in 1701
by creating the first documentary record of human activity in Western Iowa, a
description of an Ioway village northeast of the Loess Hills near Spirit Lake
(Mutel 1994). Rivers provided initial access for the traders and priests, and
later for more substantial numbers of settlers. Further inland, fur traders
followed the Indian trails. In the northern Loess Hills, these paths tended to
follow the ridge tops; farther south, they nestled in the valleys.
Westward Expansion: French fur traders and missionaries were the
first Euro-Americans to discover the Loess Hills, claiming the region for their
mother country. Following their loss of the Seven Years War in 1763, the French
transferred their claim to Spain. However, the Spanish returned the area to
France in 1800 and in 1803, France sold the area to the United States as part
of the Louisiana Purchase. The following year, President Thomas Jefferson sent
Meriwether Lewis and William Clark to explore the new territory. The expedition
spent much of July and August 1804 traveling the portion of the Missouri River
adjacent to the Loess Hills, exploring, hunting, and documenting their beauty
and bounty.
In 1833 the U.S. government relocated the Potowatomis, approximately 2,000 in
number, from Illinois to southwestern Iowa. The largest village was near modern
day Council Bluffs, with smaller villages farther south. The Potowatomis lived
primarily by hunting the gameladen Loess Hills, gathering native plants and
planting small gardens.
White settlers trickled into the Loess Hills area in the late 1830s and early
1840s. The early towns were established along transportation routes, near the
Missouri River, at the base of the bluffs, or in the valleys of the Missouri’s
tributaries.
The first steamboats began running the Missouri River to serve the fur traders
in 1831. Gradually the market changed and agricultural supplies and residential
goods became the primary cargoes. In the 1850s and 1860s, most of those coming
to Council Bluffs traveled by land to St. Louis or Jefferson City, Missouri,
then by steamboat up the Missouri River (Holt 1925). For more than a
quarter-century, Council Bluffs was the northernmost regular stop. Regular
steamboat service to Sioux City was established in 1859 (Holt 1925); and by
1860 Sioux City’s market dominated the Missouri River traffic.
Early roads went north-south along the base of the bluffs, and east-west along
river valleys when feasible. By the 1850s stagecoach service was available
along Iowa’s western border, and post offices were established in most towns
along the routes (Rogers 1990). Additional stagecoach roads traversed the
hills; the trace from Glenwood to Tabor is still easily visible along the ridge
tops (Blackburn, personal communication). Nevertheless, development of the
Loess Hills region was sparse until railroads came in the 1860s and 1870s,
permitting settlement further away from the waterways.
The Railroads: Railroad
companies promoted the area, and as soon as they published their routes, men
came to assist in constructing the railroads, and stayed to work on the
railroads or farms. Hotels were established to accommodate the laborers, and
continued to thrive on the business of rail travelers. Women made money as
laundresses and bakers, and rented rooms to boarders. Towns grew around the
railroads following a rhythmic pattern: first depots and grain storage
facilities, then businesses, and finally homes (Bonney 1994; Conard and Cunning
1990). This pattern is still evident in most railroad towns located in the
Loess Hills.
Agriculture: Nineteenth-century
farmstead development reflected a functional response to the terrain and its
suitability for agriculture. Settlers built their homes and farmsteads close to
a source of water, which could be either a creek or a spring exiting at the
base of the bluff. Prior to about 1940, farmsteads were often located on the
elevated terraces located at the base of the bluff edge, usually on the north
side of the alluvial fan of small tributaries. The main house and primary farm
structures were generally oriented to the southwest or south with bluffs
buffering the north winds. Cellars were built into the base of the bluffs.
Farmers adjusted their land use in accordance with what was available at any
particular time, cultivating the prairie tops when the valley was too marshy;
moving to the valley once the marshes were drained and all the while using the
hillsides for grazing (Sayre 1989).
The farms of Iowa produced wheat, corn, oats, grains, potatoes, sorghum, flax,
grasses/hay, root plants, “salad” plants, and other fruits and vegetables. In
addition, Iowa was fifth nationally in livestock production. In specific
categories of livestock production, Iowa ranked fourth in production of hogs;
fifth in horses; and sixth in cattle and oxen (Iowa Board of Immigration 1870).
Western Iowa's farmers were among the first to feel the effects of the
Depression. Prices for farm goods plummeted, and the agricultural depression
preceded the disastrous stock market crash by several years. During the Great
Depression, much land changed hands as banks or insurance companies foreclosed
on loans, and neighbors bought and sold parcels (Blackburn personal
communication). Hoping to stop the foreclosures, the governors of the
Midwestern farm states met in Sioux City in September 1932 to plan a program
including a moratorium on farm debts, increased credit at lower interest, and
surplus controls. About 5,000 farmers were also in attendance (Schweider 1996).
Depression-era farmers benefited greatly from New Deal programs, better farming
methods, and new technology. Technological developments with durable effects
included the electrification of rural areas, the genesis of hybrid seed corn,
and the increased availability of farm machinery (Schweider 1996). The
introduction of steam- and later, gasoline-powered machinery encouraged the use
of more land for market crops (Sayre 1989). Aerial photographs from 1938 to the
1970s show that the size of farm fields and of farms themselves increased
steadily. Rising farm product prices in the 1970s encouraged farmers to
increase the size of their land holdings and buy more machinery, thus
increasing their debt. The risk was realized in the 1980s when product prices
plummeted. By 1984, the value of farmland decreased by twenty percent from the
previous year. Many farmers, particularly those under the age of 35, were
threatened with the potential loss of their land, precipitating what became
known as the “Farm Crisis.” Agriculture-related industries also suffered. By
1987, Iowa had 22,000 fewer farms than it had in 1973 (Schweider 1996).
Conservation and Reclamation: Among
the most visible and lasting New Deal achievements in the study area was the
creation and/or improvement of public recreational facilities. Among those
accomplishments was the establishment of Stone State Park in Woodbury County
and major modifications to Waubonsie State Park in Fremont County.
Monona County hosted the Jones Creek watershed project. The Jones Creek
watershed
project was one of ten experimental land reclamation projects in
the country that were responsible for changing the direction of the nation's
land reclamation program. The success of the Jones Creek watershed project
encouraged the Soil Conservation Service (today's Natural Resource Conservation
Service) to continue the construction of “little dams” nationwide instead of
the extremely expensive "large dams" on major waterways that were
common before the test projects.
Small dams, dikes, and other erosion control features are now common in the
Loess Hills landform region.
Changes to the Landscape: Human
alterations to the Loess Hills landscape were at first small in scale; horse
hooves formed trails “where passage was easiest -through lowlands or along the
western edge of the bluffs” (Mutel 1989b). Then more dramatic changes occurred:
settlers built dams for water power; carved the bluffs to construct caves for
storage, kilns, and stables; quarried limestone, sand, gravel, shale and
construction fill; leveled bluffs to make way for cities; constructed roads and
railroads; and farmed the prairies. Settlers reshaped the valleys as well,
straightening the meandering Missouri River and its tributaries into channels
to hasten drainage and constructing dams to control flow and dikes to prevent
flooding. Some impacts were inadvertent: plowing slopes for cropland
accelerated erosion; grazing large herds of cattle degraded the prairies, also
exacerbating erosion; and baring soil for construction or recreational
purposes. Exposing the soil to water destabilized the loess, often rendering it
unable to support its own weight. Farmers cut native woodlands for construction
and fuel, and replaced them with exotic species. They simultaneously suppressed
wildfires, which allowed woody species to commence massive invasion of the
prairie grassland. River channelization and drainage projects destroyed
formerly abundant marshlands. Settlers altered native habitats and hunted many
large mammals to local extinction. The Loess Hills had been transformed.
CULTURAL RESOURCES
"The soul of a people is
the image it cherishes of itself, the aspect in which it sees itself against
its past, the attributes to which its future conduct must respond" -Archibald MacLeish, 1949
Significant Prehistoric Resources: The western Iowa fluvial
system has been extremely dynamic during the last 10,000 years (Holocene),
caused by the combination of easily eroded materials, high drainage density,
and great local relief. Major episodes of stream entrenchment and sediment
transport are recorded in numerous valley fills. This geomorphic history has
important implications for the preservation of prehistoric cultural remains.
These geological processes have served both to preserve archeological deposits
and to destroy them. Where archeological sites have not been eroded,
archeological remains of certain ages can be expected to occur within alluvial
fills that were deposited during those times. Thus, knowledge of Holocene
geomorphology not only provides clues to where sites of certain ages may be
found, but also provides an indication of the general age of archeological
deposits. Although a rich record of the prehistoric human past has been
recorded within the Loess Hills, continuing erosion of the Loess Hills means
that the potential for this prehistoric record to be expanded in the future is
great.
There are 827 archeological sites that have been recorded within the Loess
Hills, though an extremely small percentage of the region has been subjected to
intensive, systematic archeological surveys. Undoubtedly there are thousands
more that have yet to be discovered and recorded. Consequently, the
archeological resources within the Loess Hills, singly in most instances and
surely collectively, have the potential to illuminate much about prehistoric
cultures that were present in the Loess Hills.
Two archeological properties in the Loess Hills are listed on the National
Register of Historic Places--the multi-component Benson site and Pony Creek
Park (Jones 1998). The Benson site is a large, multi-component Woodland site
located in Woodbury County. It was observed in 1982 in the form of deeply buried
hearths, pottery, and other cultural debris visible in gully walls for a
distance of 2,200 feet. Components of Late Archaic, Early Woodland, Middle
Woodland, and Late Woodland age are believed to be present (Thompson 1984).
Although excavations have not taken place here, the Benson site offers
tremendous potential to yield information that will be important to
understanding major changes in cultural adaptations to late Holocene
environments (Thompson 1984). The Benson site was listed on the National Register
of Historic Places in 1984. Located in Mills County, Pony Creek Park is owned
and operated as a recreational park by the Mills County Conservation Board. It
was listed on the National Register in 1971 and contains two Nebraska Phase
earthlodge sites. Forty-six other presently recorded archeological sites in the
Loess Hills consist of two or more Native American archeological components or
occupations (Jones, personal communication). Most of these offer the potential
for comparative study, and many more will be discovered as archeological
research continues in the Loess Hills
Currently, there is no comprehensive list of archeological properties found to
be eligible for the National Register of Historic Places, although several
sites have been determined eligible, or are considered eligible by the State
Historical Society of Iowa (Jones, personal communication).
Significant Historic Resources: There are four National Historic
Landmark (NHL) properties in the Loess Hills. The following includes descriptive
information from the National Historic Landmark documentation.
Floyd Monument: Located in
Sioux City, the 100-foot-tall sandstone obelisk overlooking the Missouri River
valley commemorates the burial site of Sergeant Charles Floyd. Floyd was the
Lewis and Clark expedition's only fatality, and the first United States soldier
to die west of the Mississippi River. Lewis and Clark buried Floyd's remains
high above the Missouri both to protect the burial from flood damage and to
provide a landmark by which subsequent travelers could fix their location. The
Floyd Monument was the first property to be designated as a National Historic
Landmark under the authority of the Historic Sites Act. The monument is
publicly owned and accessible.
The Sergeant Floyd: One of few surviving U.S. Army Corps of
Engineers vessels, the survey and towboat is dryberthed on the banks of the
Missouri River at mile marker 730, adjacent to the Floyd Monument (Sioux City).
The steel-hulled, twin-screwed vessel has a steel and wood superstructure. It
measures 138.4 feet in length with a 30-foot beam, a 5.6-foot depth of hold, a
draft (fully loaded) of 3.9 feet, a height of approximately 37 feet, and a
306-ton displacement. The Sergeant Floyd was part of the federal
government's comprehensive plan for flood control and improved navigation on
the Mississippi and Missouri Rivers. It is publicly owned and accessible.
Woodbury County Courthouse: Architect William L. Steele's
Woodbury County Courthouse has been called one of the finest examples of
Prairie Style architecture in the United States. Occupying nearly a city block
in Sioux City, the basic structure is a nearly square four-story building with
an eight-story tower rising from the center core. The exterior is comprised of
granite, brick, and terra cotta punctuated with steelframed windows. The
structure, which continues to serve its original function, was designated for
its architectural significance, and does not contribute to the significance of
the Loess Hills landform region. The courthouse is publicly owned and
accessible.
Dodge House: Situated on a loess bluff in historic Council
Bluffs, this three-story, fourteen-room brick structure was designed by
architect W.W. Boyington of Chicago. Four chimneys pierce the mansard roof. The
interior is graced with black walnut woodwork, stucco medallions, and bronze
and silver hinges. The residence was designated a National Historic Landmark
for its association with Civil War General and railroad tycoon Greenville
Dodge. It does not contribute to the significance of the landform. The Dodge
House is publicly owned and accessible.
SOCIAL AND ECONOMIC
ENVIRONMENT1
Population
The people of the Loess Hills are evocative of those found in
communities and rural areas throughout much of Iowa and the Midwest. The seven
counties have a combined estimated 2000 population of just over 264,000. All
counties within the study area lost population between the 1980 and the 1990
censuses. That trend, however, has largely reversed during the 1990s. Fremont
and Monona County continued to experience a decline in population during the
past decade. Mills County, because of its proximity to the Omaha metropolitan
area, has realized the greatest expansion in population, growing by more than
11 percent during the 1990s. The racial composition of the study area is
largely Caucasian (over 96 percent of the population). Only Woodbury and
Pottawattamie Counties have non-white populations greater than one percent.
Between 1990 and 2000, most of the growth in western Iowa occurred in the
Omaha-Council Bluffs or Sioux City areas (U. S. Census Bureau 2001). Table 1
summarizes the estimated 2000 population for the seven counties, together with
recent trends in the population.

The landscape of western Iowa is predominantly rural and agricultural. A number of small communities can be found throughout the hills, in addition to portions of the metropolitan communities of Sioux City and Council Bluffs. Many of these communities have seen population trends that parallel those of the county where they are located. The populations of most communities within Fremont County have declined over the past two decades. Conversely, many of the communities in the Woodbury County, which includes Sioux City, have experienced double-digit population gains over the same period. Table 2 summarizes the estimated 1998 population for the communities of the region, together with recent trends
1 Social and economic data specific to the landform
study area as depicted in figure 1 (640,000-acres) are not available.
Therefore, unless otherwise noted, data presented in this section are
representative of the entire county or for the entire seven-county region
(3,236,108 acres).
in the population. The communities listed are those that are within the Loess Hills landform region or are along the Loess Hills National Scenic Byway.
Economy
and Tourism
As is true for western Iowa and other areas in the Great Plains, agriculture has been highly important to the Loess Hills counties. However, the nature and extent of farming is in transition. Farming is experiencing trends similar to those observed in many other agricultural regions. For example, the number of farms in the study area has steadily declined over the past three decades while, concurrently, the average size of a farm has increased. As noted previously, the farm crisis of 1984 affected the state; by 1987, Iowa had 22,000 fewer farms than it had in 1973 (Schweider 1996). Table 3 illustrates these trends.
In terms of earnings, farming is the leading economic sector for one county in the study area, Harrison County (Table 4); farming accounts for 22.7, 22.5, and 21.2 percent of the source of earnings for Monona, Harrison, and Fremont counties, respectively. Overall, the counties of the study area have a comparatively diverse economy. Manufacturing is the leading economic sector in Fremont and Plymouth Counties. The service sector is the primary sector in Monona, Pottawattamie, and Woodbury Counties. The government sector accounts for more than one-third of total earnings in Mills County.
Another noteworthy component of the Loess Hills economy is quarrying. According to data from the Iowa Department of Natural Resources (IDNR 1997), there are 27 state-licensed mining operations active in the Loess Hills; an additional 25 licensed facilities within the region are listed as "closed." Almost all of these facilities extract sand and gravel; a few quarry limestone or agricultural lime. Most operations are small businesses, employing fewer than 20 people. About one dozen such businesses operate within the counties of the study area.
Loess also is extracted from the Hills for use as construction fill and for other purposes. The "borrow pits" from which the loess is extracted scar the landscape and often are left in highly erodable conditions. Iowa statute and regulation does not consider loess a mineral, hence, the Iowa Division of Soil Conservation does not license or register sites working with just loess. As a result, the full extent and impact of loess extraction is difficult to quantify. Most units of local government do not have ordinances that are designed to protect the loess. Plymouth County, however, is working to modify its zoning ordinances to reflect protections for the Hills that were set forth in a recently adopted new comprehensive plan.
Tourism is important to the economy of western Iowa. The Loess Hills, related resources, and other nearby attractions are magnets that attract recreationists and other visitors to the region. Visitors to the area require amenities such as service stations, restaurants, and lodging. Table 4 shows that the retail and service sectors account for between 16.6 and 41.4 percent of total earnings in the seven counties of the study area.

A 1996 study by two faculty members from Iowa State University evaluated the economic impact of recreation in the Loess Hills (Alexander and Otto 1997). That study identified a range of visitation, expenditures, and related variables that can be attributed to tourism within the region. The most conservative estimates identified in the study suggest that annual recreation-related visitation to the area was about 556,900 persons. Roughly visitors to the area spent $11. 8 million per year. The average party size was about 2.4 persons, and the average daily expenditures of each party is about $51. The study estimated that these expenditures support about 231 jobs, of which about two-thirds are in the retail sector and about 30 percent in the service sector. Expenditure information cited is in 1996 dollars.
The Alexander and Otto study also found that 72 percent of respondents to their survey were local residents (defined as living within 100 miles of the point of survey). Local residents were likely to take multiple recreation trips to the Loess Hills each year (the average number of trips ranging between 7.8 and 11.6). About two-thirds of recreation visits to the region occurred on weekends, and most parties visited several sites in the area. The study found that DeSoto National Wildlife Refuge is by far the most popular single site that recreationists visit in the region; the southern Loess Hills (south of Council Bluffs) are much less frequently visited than the northern Hills.
Outdoor Recreation & Tourism Infrastructure: Tourism to the Loess Hills currently is promoted by entities such as the Iowa Division of Tourism, the Western Iowa Tourism Region, the Convention and Visitors Bureaus in Council Bluffs and Sioux City, the Welcome Centers in Harrison County (Missouri Valley) and Sioux City (the Sergeant Floyd Center), and the Loess Hills Hospitality Association.
Although some persons arrive in the area via flights to commercial airports in Sioux City, Iowa and Omaha, Nebraska, most visitors travel to the Loess Hills via automobile. A welldeveloped network of roads provides easy access to and within the region. Interstate Highway 29, a multi-state freeway connecting Canada and Kansas City, Missouri, generally runs parallel to the Loess Hills from Sioux City to the Iowa-Missouri line. Interstate Highways 80 and 680 intersect with the region in the vicinity of Council Bluffs, providing a simple "jumping-off point" for travelers from the east and the west who wish to explore the Hills. Many well-maintained state, county, and local roadways complement these highways.
The primary artery for automobile travel within the region is the Loess Hills National Scenic Byway. The Byway is a 220-mile road network that weaves throughout the landform region and nearby areas (Figure 1). The main stem of the Byway is a paved route that generally runs north to south. Sixteen loop routes that provide for short side trips enhance this primary route. The loop routes range between three and 19 miles in length, and are located along both paved and gravel roads. The main stem and the loop routes all are identified by distinctive highway signs that facilitate navigation through the Hills. A guidebook produced by the Federal Highway Administration and National Park Service (Iowa's Loess Hills Scenic Byway, date unknown) and other printed materials are available that interpret the resources of the region and direct travelers to area attractions.
Visitor services are well distributed through the Hills. Gasoline, diesel fuel, automobile service, lodging, and restaurants can be found in many communities. Hospitals or medical services are found in Sioux City, Moorhead, Missouri Valley, Tabor, Riverton, and Council Bluffs. Camping, both for tents and for recreational vehicles, is available in several locations.
Many of the attractions within the Loess Hills are related to the area's natural environment or to outdoor recreation. Both publicly and privately owned facilities provide opportunities for a wide range of outdoor recreation activities including hiking, picnicking, bicycling, horseback riding, fishing, hunting, camping, and wildlife watching. The area also provides some opportunities for winter activities such as snow skiing, sledding, and snowmobiling.
According to the Loess Hills Scenic Byway Corridor Management Plan (GHRC&D 1998), there are more than 100 parks, recreation and wildlife areas, and outdoor recreation attractions in the Byway corridor. These attractions cover more than 57,000 acres of land both within and adjacent to the Study Area. Table 5 lists over 50 of the outdoor recreation areas along the Loess Hills National Scenic Byway and within the seven-county region. The areas shown in Table 5 range between two and 9,800 acres, with the majority being less than 100 acres in size.
The DeSoto National Wildlife Refuge, located along the Missouri River in Harrison County, is the only federally owned and managed facility near the study area. The Lewis and Clark National Historic Trail (NHT), a component of the National Trails System, parallels the Loess Hills from the Missouri state line to Sioux City.
Other attractions not directly associated with the Loess Hills also encourage visitors to the region. Good potential exists to integrate promotion of the Loess Hills as a destination into the marketing programs of these other regional sites. Examples of places in or near the landform region that draw people to the area include the Sioux City Art Center, Siouxland Historical Railroad Museum, Western Historic Trails Center, General Dodge House, Mount Crescent Ski Area and several casinos. Attractions near Omaha, Nebraska also bring people to the area. These include the Henry Doorly Zoo, Joslyn Art Museum, and the Western Heritage Museum.
As part of their investigation of the economic impacts of recreation in the Loess Hills, Alexander and Otto (1997) also explored the amenities that contribute to people's enjoyment of the region's resources. The study found that those amenities that contributed most positively to recreational experiences were closely associated with the natural environment (for example, scenic overlooks, trails, interpretive signs, picnic tables, grills, etc.). Amenities perceived to have neutral or negative contributions to enjoyment of the Hills included golf courses, RV parks, hotels and motels, restaurants, and service stations.
It is important to remember that nearly three out of four
persons who participated in the study were local residents. Therefore, the
perception that amenities such as hotels, restaurants, and service stations do
not contribute to enjoyment of the area is logical, in that many respondents
could fulfill their needs for lodging, food, and fuel by returning to their
homes after a day in the Hills. Further, it is notable that the study surveyed
only persons who were already visiting the area. Perceptions of desirable
amenities might have been different if the survey had sampled potential visitors.
It is possible that the lack of certain amenities actually dissuades some
people from visiting the Loess Hills.

Land Ownership
Attesting to the rural character of the region, approximately 39,500 acres of the 640,000-acre study area are within the boundaries of incorporated areas. Hence, nearly 94 percent of the study area is unincorporated. Only 4.4 percent of the landform region is in public ownership or owned by The Nature Conservancy, a private conservation organization (Figure 3). The vast majority of the region is privately owned. Table 6 depicts private and public ownership within the landform study area, organized by county.
Overall land-cover patterns within the study area also reflect its rural character. Land cover is a generalized description of basic characteristics of the land as it appears on satellite imagery or aerial photography.
Land cover provides an approximation of land use within an area. Table 7 shows that 86 percent of the landform region is covered by grassland or row crops. These land covers are most prevalent in Woodbury County (91.3 percent) and least common in Fremont County (67.5 percent). Fremont County does have the highest percentage of wooded area (30.6).
Development of the landform region as evidenced by the “artificial” classification is most prevalent in the Council Bluffs/Omaha area (Pottawattamie and Mills County) and near Sioux City (Woodbury County).
The land use and land cover patterns described in Table 7 are derived from 1992 satellite imagery. Unfortunately, more recent data are not readily available that would allow for measurement of changes in these patterns. However, it is indisputable that changes are occurring within the Loess Hills landform region. These changes have the potential to drastically alter the character of the Loess Hills in some locations. Significant urban expansion is occurring in the Omaha, Council Bluffs, and Sioux City metropolitan areas. As a result, many areas in Mills, Pottawattamie, and Woodbury Counties are being converted from agriculture or natural land uses to residential and other types of built environments. The same trend is occurring, albeit to a lesser extent, in the other counties of the study area.
The scenic character that makes the Loess Hills so very attractive to recreationists is the same character that makes the landscape highly desirable as a place to build homes. Growth in residential development in the counties
of the study area, as evidenced through the number of permits issued for new
private housing units, has shown a generally upward trend over the past two decades. Further, the demand has accelerated during the 1990s. Between 1979 and 1990, the average annual number of private housing units authorized by building permits for the entire sevencounty region that includes the study area was 412.
During the period of 1991-1997, the average annual number of permits was 925 (an increase of more than 124 percent). Of the entire seven county area, Woodbury and Mills Counties experienced the greatest percent change in the annual number of building permits issued from 1991-1997 as compared to the average issued between 1979 and 1990 (U.S. Census Bureau 1998). It is important to note that these statistics are for the counties as a whole, and not just for the study area. However, the desirability of the Loess Hills as a place to build homes would suggest that the study area itself experienced a similar, if not greater, level of growth in new housing starts.
This increase in residential development often has resulted in a corresponding decrease in the number of acres in agricultural land. Although most buyers of agricultural land in Iowa continue to be farmers who are increasing the size of their holdings, about 30 percent of purchases made in 1999 were by investors (Iowa State University 2000).

Generalized
Description of Land Cover Categories
Grassland - consists of non-woody surfaces such as prairies,
wetlands, pastures, lawns, golf courses, hay fields. Row Crops - consists
mostly of agricultural crops (especially soybeans & corn).
Woodland - deciduous and coniferous forests, highly mixed grass
& trees, windbreaks, & dense shrubs. Artificial - pavement,
concrete, roofing materials, metal structures. This classification includes
roads, parking lots, buildings, etc.
Barren/Flood - natural surfaces covered with bare soil, gravel, &
sand bars. Includes gravel pits, rock quarries, feedlots, & construction
sites.
Water - includes lakes, reservoirs, large rivers & streams,
sewage lagoons, and open water in wetlands.
Land values within the study area have steadily increased since the
mid-1980s. Appreciation in land values within six of the seven counties within
the study area has outpaced the growth of land values in Iowa as a whole. Five
of the seven counties have experienced a more than two-fold increase in average
land values since 1985. The largest percentage gain in land value was in
Plymouth County (116.4 percent); the smallest percent gain was in Fremont
County (80 percent). Respondents to a 1999 survey conducted by Iowa State University
(Iowa State University 2000) identified five factors as having the most
positive impacts on land values during 1999: government program payments,
interest rates, crop yields, the supply of land available, and demand by
investors. Figure 4 illustrates trends in the average value of farmland since
1985.

(Values are for the entire county, including areas outside the study area)
All counties within the landform region except Mills have countywide zoning ordinances in place. However, none of those ordinances have regulations specifically designed to address issues that are threatening the Loess Hills. These ordinances do not protect the region from insensitive residential, commercial, industrial, and agricultural developments. No tools are in place to help preserve the scenic attributes of the Hills. Excavation and quarrying within the Hills continues to erode the landscape and alter the natural configuration of the skyline and horizon.
Conservation
Programs and Land-Use Planning
A number of state and federal conservation programs are contributing staff and funding for erosion control, wildlife habitat and water quality improvement, and prairie restoration programs in the Loess Hills. The Loess Hills Alliance (LHA), Fish and Wildlife Foundation, Golden Hills Resource Conservation and Development, Iowa Natural Heritage Foundation, Natural Resource Conservation Service, Soil and Water Conservation Districts, The Nature Conservancy, and other groups continue to provide information and services associated with a variety of conservation programs. In 2000, the LHA provided funding and matching grant opportunities that resulted in over $750,000 of land protection or economic growth projects (Loess Hills Alliance 2000). An ongoing effort, the Whole Farm planning initiative is utilized by six of the seven counties included in the Loess Hills landform region. Designed as a matching grants program with local Soil and Water Conservation Districts (SWCD) and in cooperation with the Iowa Division of Soil Conservation, local SWCD were able to promote and complete whole farm plans on 250 acres of private land. Whole farm plans are designed to encourage landowners to make maximum use of available state and federal soil, water, wildlife, and conservation programs (Loess Hills Alliance 2000). Most recently, $250,000 has been earmarked under the Farmland Protection Program (FPP) to preserve the Loess Hills from non-agricultural development.
The Nature Conservancy, Fish and Wildlife Foundation, the U.S. Fish and Wildlife Service, and the National Park Service have provided landowner assistance (funding, staff, and/or equipment) for prairie restoration, woody plant and exotic species control, and workshops on fire ecology and the use of prescribed fire. Other federal programs, such as the Conservation Reserve Program, Partners for Fish and Wildlife, Stewardship Incentives Program and the Wetlands Reserve Program are available to assist private landowners.
A number of comprehensive planning and zoning efforts are underway. In 2001, the LHA began soliciting requests for proposals to prepare a Comprehensive Plan for the sevencounties of the Loess Hills. This Plan will document existing studies, and other land-use data and serve as a template for counties in the Loess Hills to use (Sproul 2001). Plymouth County recently adopted an updated Comprehensive Plan that includes specific measures designed to control growth and protect the landforms; the county is proceeding to update its zoning regulations to reflect policies in the new plan. Two other counties, Mills and Woodbury, are developing Comprehensive Plans. The LHA is also developing a grant program to encourage county and city governments to undertake comprehensive planning and zoning which consider critical resource protection strategies for the Loess Hills landform.
Finally, the Loess Hills Scenic Byway Corridor Management Plan (Golden Hills Rural Conservation Development 2000) is a useful tool available for land use planning. The Byway Plan identifies important resources and includes model ordinances designed to preserve the integrity of the resources in the Loess Hills.
