3 The Louisiana Purchase
Jefferson thought there might be a water route that stretched all the way across the country from the Mississippi River to the Pacific Ocean. He paid Meriwether Lewis and William Clark to check it out. They formed a team of 45 men called the Corps of Discovery. Meriwether Lewis William Clark

4 The Expedition In 1804, the Corps of Discovery left the Mississippi River at St. Louis. They travelled down the Missouri River as far as they could go. Half way down the Missouri River, Lewis and Clark hired a fur-trader named Toussaint Charbonneau. His wife, Sacagawea was very helpful to the Corps, because as a Shoshone, she knew how to translate for some of the Native American tribes that Lewis and Clark encountered. Sacagawea

5 The Expedition Once they got to Great Falls the Missouri River turned South. The expedition struggled to find a pass through the Rocky mountains when they reached the Continental Divide. After splitting up Lewis and Clark both arrived at the Pacific Ocean in the Oregon Territory.

6 Outcome of the Expedition
While exploring, the Corp of Discovery did not find a water route to Pacific Ocean, nor did they blaze a path for future settlers. They did bring back important maps of the regions they explored, information about plants and animals that lived west of the Mississippi River and established peaceful relationships with some of the Native American tribes that they met.
