On May 14, 1804 William Clark and his four dozen men left their St. Louis camp to meet with Meriwether Lewis. The men met going upstream the Missouri river on May 20, 1804 starting the Lewis and Clark expedition. Clark would stay aboard the keelboat to chart the course and make maps when Lewis went to study the different rock formations, soil, animals, and plants on land. They tried to make camp along the river when they could and used night guards in case they encountered any Indians. Lewis and Clark, along with their men, traveled more than 600 miles up the Missouri by the end of July.
