Remarkable Formations on the Banks of the Upper Missouri

Description

Again on August 6 Maximilian observed that the high, crumbling banks of the Missouri presented increasingly dramatic formations resembling the ruins of old castles and fortresses. He remarked that "I have not yet read anything about these strange mountain formations and an exact description might certainly not be without interest for the European reader." Elsewhere he explains that "Lewis and Clark gave a short description of this remarkable tract without, however, knowing the name of Stone Walls, which was added later."
