East Wyoming is a geographically diverse region that is home to mountain ranges, rolling meadows and arid desert. Historic cities, national landmarks and a large number of guest ranches encompass the spirit of the American West, which is accented by ranching traditions and rodeo exhibitions. As an original cattle town located on the western edge of the Great Plains, Cheyenne is the state capital and Wyoming's largest city. The towns of Buffalo and Sheridan sit at the foot of the Big Horn Mountains, offering outlets for excellent hunting and fishing opportunities. Devil's Tower National Monument, a 60-million-year-old volcanic mass, has strong cultural and religious significance, while the southeastern part of the state boasts the Medicine Bow Mountains and Laramie, a settlement that lays claim to an abundance of museums, including the University of Wyoming Geological Museum.
