Lewis and Clark Expedition Sights Pacific Ocean
The Lewis and Clark Expedition, commissioned by President Thomas Jefferson after the Louisiana Purchase, aimed to explore the American West, map routes to the Pacific, and establish U.S. claims. After traversing the Rocky Mountains and navigating the Columbia River system through challenging terrain and weather, the Corps of Discovery reached the river's estuary. On November 7, 1805, William Clark recorded in his journal the sighting of what they believed was the Pacific Ocean, exclaiming 'O! the joy.' The party spent the following weeks exploring the area amid rain and tides before establishing winter quarters at Fort Clatsop.
