Where did the Lewis and Clark trip begin and end?

Answer 1

Contrary to popular belief, the expedition DID NOT begin in St. Louis, Missouri. The first entry in the Lewis and Clark Expedition Journals state that the journey began in Pittsburgh, PA on August 30, 1803. Lewis, who had been assigned by Jefferson sailed down the Ohio River with supplies towards St. Louis.

William Clark would offer to join Lewis on the expedition weeks later on October 13, 1803 at Camp Dubois (in present-day Indiana). They then named their team the "Corps of Discovery." From there, they sailed down the Ohio River towards St. Louis. Meriwether Lewis had spent the time prior to their departure in St. Louis gathering information from mountain men returning from the west. They then departed St. Louis in May 1804 heading up the Missouri River.

The explorers began their journey home on March 23, 1806. On July 3, after crossing the Continental Divide, the Corps split into two teams so Lewis could explore the Marias River. Lewis and Clark stayed separated until they reached the confluence of the Yellowstone and Missouri Rivers on August 11. Once reunited, the Corps was able to return home quickly via the Missouri River. They reached St. Louis on September 23, 1806.
