The Glenrock Buffalo Jump encompasses three features: a large flat plateau which extends to the edge of a 40 foot bluff that served as the ''jump-off'' point. Below the bluff is several dry washes extending down a steep talus slope. Large quantities of buffalo bones and other cultural remains are deposited in the soil of the talus slope.

The Late Prehistoric site dates to approximately A.D. 400 to A.D. 1750. Archaeological investigations have revealed up to four feet of deposits indicating several periods of use. Buffalo jumps were an important part of the Northwestern Plains prehistory. They represented a stylized pattern of food procurement for a long period of time.
