Lewis and clark expedition route

Lewis and Clark began their journey by setting off on the Ohio River on August 31, 1803. Then, on May 14 of the next year, they began traveling on the Missouri River. The Corps spent the winter of 1804-1805 with the Mandan tribe. Once they left the Mandan, they continued traveling down the Missouri River and eventually hit the Bitterroot Mountains. It took the group 11 days to cross the Bitterroots. After emerging from the mountains, the Corps rode the Clearwater River, which led to the Snake River, which itself eventually lead to the Columbia River. In the middle of November of 1805, they finally reached the Pacific Ocean.
