Loess Hills in Western Pottawattamie County
Urban development is rapidly taking place in the Loess Hills. The Loess Hills are Western Pottawattamie County's most distinctive landscape and Iowa's most fragile landform in susceptibility to erosion. When loess soils are disturbed, the threat to surface water is significant. Soil erosion rates are so high that the amount of eroded sediment carried in streams draining the Loess Hills is among the highest in the United States.
