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.
Navajo-Churro The Navajo-Churro, or Churro for short, (also American or Navajo Four-Horned) is a breed of domestic sheep originating with the Spanish Churra sheep obtained by Navajo, Hopi and other Native American nations around the 16th century during the Spanish Conquest. The breed is renowned for its hardiness and adaptability to extremes of climate. Its wool consists of a protective topcoat and soft undercoat. Some rams have four fully developed horns, a trait shared with few other breeds in the world. The Navajo-Churro has also gained popularity for its low-maintenance reputation, resistance to disease, and lean meat. Some say they are very personable. Ewes often birth twins. This breed is raised primarily for wool.
