Lewis and Clark Expedition

from 14 May 1804 to 23 September 1806

The Lewis and Clark Expedition, also called the Corps of Discovery, was an overland journey to the Pacific coast of North America led by Meriwether Lewis and William Clark. It was commissioned by President Thomas Jefferson soon after the Louisiana Purchase of 1803 to explore the new territory, to look for a water route across the continent, and to study its geography, plants, animals and Native peoples. The party set out from the Missouri River near St. Louis in 1804, wintered with the Mandan, and was guided through the Rocky Mountains with the help of Sacagawea, a Shoshone woman, who traveled with her infant son. It reached the Pacific in late 1805, spent the winter at Fort Clatsop, and returned in September 1806. The expedition produced detailed maps and journals, though it also opened the way for American expansion.
