What animal did Lewis and Clark newly discover during their 1804 expedition up Old Baldy in Nebraska?
Black-tailed prairie dog The black-tailed prairie dog ("Cynomys ludovicianus"), is a rodent of the family Sciuridae found in the Great Plains of North America from about the United States-Canada border to the USA-Mexico border. Unlike some other prairie dogs, these animals do not truly hibernate. The black-tailed prairie dog can be seen above ground in midwinter. A black-tailed prairie dog town in Texas was reported to cover 64000 km2 and included 400,000,000 individuals. Prior to habitat destruction, this species may have been the most abundant prairie dog in central North America. This species was one of two described by the Lewis and Clark Expedition in the journals and diaries of their expedition.
Mahtotopa Mountain Mahtotopa Mountain (8677 ft ) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. Mahtotopa Mountain rises to the south above Saint Mary Lake midway between Red Eagle Mountain and Little Chief Mountain and can be easily seen from the Going-to-the-Sun Road to the southwest of Rising Sun. Originally named "Four Bears Mountain" by George Bird Grinnell in 1885, the name was changed in 1932 to Mahtotopa. "Mahtotopa" is an incorrect spelling of "Mato-tope", the Mandan chief known as "Four Bears". Mato-tope was a grandfather of Joe Kipp, a hunting companion of Grinnell.
