The Loess Hills, a 200-foot-thick deposit of windblown silt, dominate the Iowa portion. These steep, narrow ridges are a globally rare landform. The Nebraska Sandhills, a vast expanse of grass-stabilized dunes, cover the final stretch. Both regions offer striking vistas and unique ecosystems.

UNESCO World Heritage Sites are absent from this direct route, but the Lewis and Clark National Historic Trail (a National Historic Trail) runs parallel for many miles. For international travelers, this route provides an authentic American plains experience without the crowds of national parks.
