The rich, fertile soil along with the proximity to fresh water, brought the Flathead, Bannock and Shoshone Indians to the region and later trappers and settlers, and now this beautiful land has been preserved as a state park for visitors just like you.

In addition to its vast natural resources and outdoor activities, Missouri Headwaters State Park also boasts extensive cultural history - ranging from the tribes that lived there beginning 3,000 years ago to Lewis and Clark to fur traders to settlers.
In late July 1805, William Clark and a small number from the Corps of Discovery reached the Headwaters while scouting for Shoshone Indians, whom they hoped would sell them horses. It was Sacajawea, who recognized the area as where she was captured as a child by the Hidatsa, that led the expedition successfully there.
While at the confluence, Clark left a note for Meriwether Lewis to find and later, Lewis Rock was named for him.
