Electric Peak is the tallest mountain in the Gallatin Range of southern Montana, close to the Wyoming border and rising to an altitude of 10969 ft. The peak has some of the greatest physical relief in Yellowstone National Park, rising 3389 ft above its base. Electric Peak was named during the first ascent in 1872 by the United States Geological Survey. Members of the Hayden Survey led by Henry Gannett experienced electrical discharges from their hands and hair after a lightning event on the summit.
