Quake Lake (officially Earthquake Lake) is a lake in the western United States, on the Madison River in southwestern Montana. It was created after an earthquake struck on August 17, 1959, with 28 fatalities.[4] Northwest of West Yellowstone, Quake Lake is six miles (10 km) in length with a maximum depth of 125 feet (38 m).
U.S. Route 287 follows the lake and offers glimpses of the effects of the earthquake and landslide, and a visitor center is just off the road. The lake is mostly within Gallatin National Forest.
