Pikes Peak (Missouri)
Pikes Peak most likely takes its name from the taller Pikes Peak, in the Rocky Mountains.
Zebulon Pike
Zebulon Montgomery Pike (January 5, 1779 – April 27, 1813) was an American brigadier general and explorer for whom Pikes Peak in Colorado was renamed (from El Capitan). As a U.S. Army officer he led two expeditions under authority of third President Thomas Jefferson through the new Louisiana Purchase territory, first in 1805-06 to reconnoiter the upper northern reaches of the Mississippi River, and then in 1806-07 to explore the Southwest to the fringes of the northern Spanish-colonial settlements of New Mexico and Texas. Pike's expeditions coincided with other Jeffersonian expeditions, including the Lewis and Clark Expedition (1804–1806) and the Thomas Freeman and Peter Custis expedition up the Red River (1806).
