Geography
The Eastern Plains are part of the High Plains, which are the westernmost portion of the Great Plains. The region is characterized by mostly rolling plains, divided by the South Platte River and Arkansas River valleys. There are also several deciduous forests, canyons, buttes, and a few large natural lakes and rivers throughout the region. The Eastern Plains rise from approximately 3,400 feet (1,000 m.) at the eastern border of Colorado with Kansas, where the Arkansas River leaves the state, to 7,500 feet (2,300 m.) east of the Denver Basin.
