1988 Map of Earthquake Lake

USGS Topo · Published 1988

About this map

The Madison Slide dominates this landscape, a massive debris field that dammed the Madison River to form Earthquake Lake. This 1988 provisional map documents the geographic aftermath of the 1959 Hebgen Lake earthquake, showing the Earthquake Memorial and Visitors Center established to commemorate the event. The map captures a transition point where the river leaves its natural channel and fills the canyon, surrounded by the high peaks of the Horn Mountains and Sheep Mountain. Within the Lee Metcalf Wilderness and Gallatin National Forest, the terrain is marked by steep drainages like Eagle Creek and Rock Creek. To the west, the topography levels into the Missouri Flats, where a Quarry and various section lines indicate localized human activity and land management amidst the protected wilderness areas.
