About this map

Earthquake Lake and the Madison River dominate this landscape, reflecting a site defined by geologically recent seismic activity. The map identifies the Earthquake Lake Dam and the Earthquake Memorial, signifying the area's importance as a place of both natural hazard and remembrance. Ranching life is documented through scattered family holdings such as Olifee Ranch, Stagger Ranch, and Shaw Ranch, positioned near the flowing waters of Mile Creek and Rock Creek.

The terrain rises sharply toward the Henrys Lake Mountains, where peaks like Sheep Mountain and The Horn tower over the drainage basins. Recreation is central to the area's modern character, with both Beaver Creek Campground and Rock Creek Campground providing access to the shorelines. This topographic study captures a remote corner of the Montana-Idaho border where the local economy and geography remain deeply tied to the river valleys and high alpine ridges.
