Lewis and Clark
Meriwether Lewis and William Clark were the first Americans to investigate the Great Plains. In 1803 President Jefferson appointed Lewis, his private secretary, as leader of the Corps of Discovery, and Lewis offered Clark an invitation to be co-commander. The Corps passed through this portion of the middle Missouri River from August 20 to September 8, 1804, and then on the return trip from August 31 to September 4, 1806.

Daily Activities - Extraordinary And Rare
On the cross-country trek to Spirit Mound, Clark took a singular temperature reading during a period when he made no other weather observation. The expedition moved into unfamiliar environmental zones with a changed climate and terrain, primarily west of today's Niobrara, Nebraska. Like so many points on the compass of Lewis and Clark's exploring world, the journey along this stretch of the river was ordinary and routine at the same time that it was extraordinary and rare. It holds both a standard and a special place in the history of the expedition.
