supports: The Wildcat Hills are an escarpment between the North Platte River and Pumpkin Creek in the western Panhandle, in the state of Nebraska in the Great Plains region of the United States. Located in Banner, Morrill, and Scotts Bluff counties, the high tableland between the streams has been eroded by wind and water into a region of forested buttes, ridges and canyons that rise above the surrounding landscape. An escarpment is a steep slope or long cliff that forms as an effect of faulting or erosion and separates two relatively level areas of differing elevations. Usually "escarpment" is used interchangeably with scarp (from the Italian "scarpa", shoe). But some sources differentiate the two terms, where "escarpment" refers to the margin between two landforms, while "scarp" is synonymous with a cliff or steep slope. The surface of the steep slope is called a scarp face.This (escarpment) is a ridge which has a gentle(dip) slope on one side and a steep (scarp) slope on the other side. The North Platte River is a major tributary of the Platte River and is approximately long counting its many curves. It travels about distance. Its course lies in the U.S. states of Colorado, Wyoming, and Nebraska. The Great Plains is the broad expanse of flat land (a plain), much of it covered in prairie, steppe and grassland, that lies west of the Mississippi River tallgrass prairie states and east of the Rocky Mountains in the United States and Canada. This area covers parts, but not all, of the states of Colorado, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, and Wyoming, Minnesota, Iowa and the Canadian provinces of Alberta, Manitoba and Saskatchewan. The region is known for supporting extensive cattle ranching and dry farming. A butte is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller than mesas, plateaus, and table landforms. The word butte comes from a French word meaning "small hill"; its use is prevalent in the Western United States, including the southwest where "mesa" is also used for the larger landform. Because of their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas. 
  In differentiating mesas and buttes, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height. Bighorn Mountain , or He Sha , is located in Banner County , about 10.8 miles ( 17.4 km ) east of the county seat of Harrisburg , in the Wildcat Hills . The peak was named for the bighorn sheep that once roamed its flanks , and were reintroduced in the 1970s . Many residents of the county have carved their names at the top of the peak ; the practice dates back at least to 1887 . A canyon (Spanish: cañón) or gorge is a deep cleft between escarpments or cliffs resulting from the erosive activity of a river over geologic timescales. Rivers have a natural tendency to cut through underlying surfaces so will eventually wear away rock layers to lessen their own pitch slowing their waters; given enough time, their bottoms will gradually reach a baseline elevationwhich is the same elevation as the body of water it will eventually drain into. This action, when the river source and mouth are at much different base elevations will form a canyon, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. Nebraska is a state that lies in both the Great Plains and the Midwestern United States. The state is bordered by South Dakota to the north, Iowa to the east and Missouri to the southeast, both across the Missouri River, Kansas to the south, Colorado to the southwest and Wyoming to the west. Its area is just over 77,220 sq mi (200,000 km) with almost 1.9 million people. Its state capital is Lincoln. Its largest city is Omaha, which is on the Missouri River.
