President Thomas Jefferson appointed Captain Meriwether Lewis and 2LT William Clark to find a northwest passage to the Pacific Ocean. In May 1804, The Corps of Discovery Expedition set out to complete the mission they were given. In October 1805, the explorers camped overnight on an island close to the confluence of the Snake and Clearwater Rivers. This is near where Lewiston, Idaho, and Clarkston, Washington, can be found today.
