Overview

About This Attraction

Turquoise water runs along a six-mile-long lake, set against a broad landslide scar on Sheep Mountain. The lake formed when a massive rock avalanche dammed the Madison River during the 1959 Hebgen Lake earthquake. It stands as a stark, real-world example of tectonic forces reshaping the landscape in moments.

Best Time to Visit

Summer (late May–mid-September) when the Earthquake Lake Visitor Center is open and roads are clear; sunrise and sunset yield the best light.

Visitor Tips

  • Look for the broad landslide scar along Sheep Mountain from the visitor center overlooks.
  • The Madison River water is bitterly coldβ€”dress in layers and be prepared for wind.
  • Bear spray is recommended in this wildlife-rich area.
  • Stay on designated paths and overlooks; rockfall remains a risk near the scar.
  • Parking can fill on peak days; plan accordingly.
