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.
John and Louise Seier National Wildlife Refuge John and Louise Seier National Wildlife Refuge is located in the U.S. state of Nebraska and includes 2,400 acres (9.71 km). The refuge protects a portion of the largest remaining area of tall and mid grass prairie remaining in the U.S. Collectively known as the Sand Hills region of Nebraska, the dunes were the end result of the last ice age known as the Pinedale glaciation. During the Holocene glacial retreat the sand dunes that been deposited in their current location by the vast continental glaciers, were exposed and grasses eventually took over. The refuge is managed by the U.S. Fish and Wildlife Service and along with Fort Niobrara and Valentine National Wildlife Refuges, form the Fort Niobrara National Wildlife Refuge Complex.
