1988 Map of Eureka Basin

About this map

The Eureka Basin landscape is defined by the high-altitude divide where the Ruby River and the West Fork Madison River originate. This 1980s provisional study documents a rugged interior within the Beaverhead National Forest, characterized by steep drainages like Poison Creek and Murphy Creek. Human presence is sparse, marked primarily by resource extraction and forest management infrastructure. An Adit and Mine Shaft in the northern basin point to historical prospecting efforts, while the West Fork FS Station and Roadside Park near the Gravelly Range reflect the area's role as a managed wilderness. Numerous named water sources, including Long Spring No 1 and Fish Creek Lake, highlight the complex hydrology that feeds the larger river systems of the Montana Rockies.
