William Clark, Mapping the American Frontier

Summary

In October 1804, William Clark and Meriwether Lewis, leaders of the Corps of Discovery, arrived near present-day Bismarck, North Dakota, to explore the vast Louisiana Purchase. They sought to chart a Northwest Passage, relying on Native American guidance. Over the next two years, Clark meticulously mapped the Missouri River, the Rockies, and the Oregon Territory, documenting native cultures and landscapes. Despite discovering no Northwest Passage, the expedition reached the Pacific Ocean in 1805. Clark's detailed maps and observations guided westward expansion, and he served as a key figure in managing Native American relations until his death in 1838.
