Upper Missouri

Description

Approximately ten miles above the mouth of the Judith River, the Arrow River, formerly the Slaughter River of Lewis and Clark, enters the Missouri channel from the south. Beyond this point the Missouri takes a decidedly northward course for some miles through a region named the Stone Walls. Approaching this area on August 5, Maximilian remarked in his journal that the keelboat was making its way through remarkably scenic country. Bodmer's study of unusual formations along the banks in this vicinity was made on August 5 or 6.
