The expedition camped at the confluence of the Osage and Missouri rivers between June 1 and June 3, 1804. As they waited for the arrival of George Drouillard and John Shields, who were traveling separately on horseback, Lewis and Clark took measurements and recorded observations. Clark climbed the hill behind their camp on June 2, noting in his journals that he “assended the hill in the point 80 ps. from the pt. found it about 100 foot high, on the top is 2 graves, or mouns, a Delightfull prospect from this hill which Comds. both rivers.”
Although the confluence of the two rivers was visible from Clark’s Hill in 1804, it subsequently shifted to a location approximately six miles further downstream. However, the woodland character of the river valley remains intact and visitors are afforded views that are relatively undisrupted by modern intrusions. The site is operated as a state park unit, and features a hiking trail that accesses a viewing platform over the rocky outcrop that Clark stood upon. The two burial mounds documented by Clark remain intact, and have been dated to the Late Woodland period (BCE 600-900). Three additional mounds and a village site have also been located in the area.
