How much did the U.S. government give Lewis and Clark for their expedition?

In 1803, the U.S. Congress granted Lewis and Clark $2,500 for an expedition to explore the territory west of the Mississippi River.

Selected by President Thomas Jefferson to lead the group of 50 people were Meriwether Lewis and William Clark.

Starting out from St. Louis, Missouri, the expedition crossed the Rockies and reached the Pacific coast of what is now Oregon before returning to St. Louis in 1806.
