Electric Peak is the highest mountain in the Gallatin Range in southern Montana near the Wyoming border, in the northern part of Yellowstone National Park. Rising 10,969 feet above sea level and 3,389 feet above its base, it has some of the park’s strongest local relief and stands out among Yellowstone’s rugged northern mountains. The peak received its name during its first recorded ascent in 1872, when members of the Hayden Survey led by Henry Gannett reached the summit and, after a lightning event, experienced electrical discharges from their hands and hair. Its name preserves a vivid moment from the era of early government surveys in the American West.
