..."'' The expedition were likely the first white men to ever penetrate this landscape. Lewis and Clark were at first uncertain how to proceed, and scouted each of the branches before ultimately departing on July 30 up the Jefferson River. The expedition also passed the forks on its return journey on July 13, 1806. As the west was explored and developed through the 19th century, the forks area was frequently used as a camp site by fur trappers. Acquisition for the state park was begun by preservation organizations in the 1960s.

The Missouri traditionally had been called the longest river in North America. However, 72 miles of it have been trimmed off in re-channeling its streambedmainly for the many
