Great Barrel Horse

In the 18th century, the area around the confluence of the Platte and the Loup Rivers was used by a variety of Native American tribes, including Pawnee, Otoe, Ponca, and Omaha. The Pawnee are thought to have descended from the Protohistoric Lower Loup Culture; the Otoe had moved from central Iowa into the lower Platte Valley in the early 18th century; and the closely related Omaha and Ponca had moved from the vicinity of the Ohio River mouth, settling along the Missouri by the mid-18th century. In 1720, Pawnee and Otoe allied with the French massacred the Spanish force led by Pedro de Villasur just south of the present site of Columbus. In the 19th century, the " Great Platte River Road"—the valley of the Platte and North Platte Rivers running from Fort Kearny to Fort Laramie— was the principal route of the westward expansion. For travellers following the north bank of the Platte, the Loup River, with its soft banks and quicksands, represented a major obstacle.
