Arrow Rock was the name of a prominent flint-bearing bluff on the Missouri River. The name first appeared on a French map from 1732 as "Pierre a Fleche", meaning "Rock of Arrows". Edwin James on the 1819 Yellowstone Expedition wrote, "Arrow Rock is so called from its having been formerly resorted to by neighboring Indians for the stone used to point their arrows." The two dominant Native American tribes in the area encountered by French traders early in the 18th century were the Missouria and the Osage.
