Throughout the 19th century Congress promoted exploration of the American West. President Thomas Jefferson proposed, and Congress funded the first expedition: a “Corps of Discovery,” led by Meriwether Lewis and William Clark in 1803. Their mission was to chart the Louisiana Territory, find a water route to the Pacific Ocean, and establish trade with Indian nations. Traveling the Missouri and Columbia Rivers and partially overland to the Pacific, they acquired a wealth of information about the geography, geology, flora, fauna, and peoples of the Northwest.
