Madison Buffalo Jump State Park is a Montana state park located seven miles south of the Interstate 90 interchange at Logan in Gallatin County, Montana in the United States. The park preserves a canyon cliff used by Native Americans as a buffalo jump, where herds of bison were stampeded over the cliff as an efficient means of slaughter. The main geographic features of the jump site remain largely unchanged since the days of the jumps. Archaeologists have found tons of bison bones buried at the base of the cliffs. They have also uncovered the remains of tipi villages.
