West Butte is a 6,983-foot-elevation (2,128-meter) mountain summit located in Toole County, Montana, United States.

West Butte is an exposed laccolith composed of diorite porphyry and monzonite which was created by an igneous intrusion through older Mississippian sedimentary rocks during the Eocene, about 50 million years ago.

The Sweet Grass Hills, which are centered in buffalo hunting territory, are sacred to the Blackfoot and other tribes.

The wettest period of the year is generally May through August, with up to 20 inches of precipitation falling annually on the peak.
