The Lewis and Clark Expedition is also referred to as the Corps of Discovery by historians
Lewis and Clark 'discovered' animals that they had never heard of including the prairie dog and the grizzly bear.
After the successful expedition Lewis became governor of the Louisiana Territory and Clark became governor of the Missouri Territory. Clark also served as Superintendent of Indian Affairs for several years before his death
In March of 1806 the expedition left on the return journey, which took only about six months. The entire journey to the west coast and back was approximately 7000 miles.
Along the expedition Lewis and Clark traded with Native American tribes, who helped them by showing them which plants were safe to eat
