Walk in the footsteps of the Lewis and Clark Expedition at Clark’s Hill/Norton State Historic State. The explorers camped at the base of Clark’s Hill between June 1 and June 3, 1804, on their epic journey. Wiliam Clark climbed the hill on June 2 and saw a sweeping vista that included the confluence of the Missouri and Osage rivers.  Today, a short trail takes visitors past two Indian mounds mentioned by Clark in his journals and to an overlook that shows where Clark stood more than 200 years ago.
