1988 Map of Eureka Basin

About this map

The Beaverhead National Forest defines this high-elevation landscape in the late 1980s, characterized by the steep divide of the Gravelly Range and the headwaters of several critical drainages. The Eureka Basin sits at the heart of the map, where the complex hydrology of the West Fork Madison River and the Ruby River begins to take shape. Evidence of mineral exploration and land management is scattered throughout the terrain, including a Mine Shaft, an Adit, and multiple coal outcroppings along Coal Creek. This provisional survey illustrates a working wilderness where recreational and administrative infrastructure, such as the West Fork FS Station and Roadside Park, meets the industrial history of the Montana mountains. The presence of the Gravelly Range Road provides the primary access through this remote portion of Madison and Beaverhead Counties, connecting secluded water sources like Lone Willow Spring and Fish Creek Lake.
