Quake Lake is just outside West Yellowstone and a part of Hebgen Lake. In 1959 an earthquake hit, killing 28 people while also causing an 80-million ton landslide to form a dam. Supposedly the 28 people killed were all campers in the way of the 100 mile per hour landslide.
The lake is clogging up the Madison River so taking the drive down HWY287 gives you the opportunity to fish the lake and the river. There’s also quite a few campgrounds between the short stretch from Hebgen to Quake Lake.
