2024 Map of Earthquake Lake

About this map

Earthquake Lake dominates this rugged high-country landscape, formed by the massive 1959 seismic event that triggered the Madison Slide. The Madison River flows through the canyon floor, flanked by the Lee Metcalf Wilderness to the north and the Henrys Lake Mountains to the south. This modern survey illustrates the proximity of the Continental Divide and the intersection of the Madison and Gallatin county lines. Small settlements and ranch sites like Brown, Torry, and the Continental Divide Ranch are scattered near the river valley. The map details the network of forest roads and trails, including Sheep Creek Rd and the Sheep Lake Trl, which provide access to high-altitude features like Sheep Mtn and the isolated Sheep Lake.
