Inscription. Tower Rock marks he (sic) point where the Corps of Discovery left the plains and entered the Rocky Mountains The point where they left the familiar prairies and entered an new terrain.
Only July 16, 1805 Lewis recorded that "at this place there is a large rock 400 feet high which stands immediately in the gap which the missouri makes on a passage from the mountains: it is insulated from the neighboring mountains by a handsome little plain which surrounds its base on 3 sides and the Missouri washes its base on the other... this rock I call the tower. It may be ascended with some difficulty nearly to it's summit, and from it there is a pleasing view of the county we are now about to leave.:
