Quake 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. Northwest of West Yellowstone, Quake Lake is six miles in length with a maximum depth of 125 feet.
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.
