About this map

Lolo National Forest and Deerlodge National Forest meet in this mountain survey of Granite County, revealing a landscape defined by mining history and steep drainage basins. High peaks like Sliderock Mountain and Spink Point overlook a network of narrow gulches and creeks, including Eightmile Creek and Harvey Creek. The presence of several distinct operations, such as the Edelman Mine, Alps Mine, and the Jumbo Mine, indicates a period of persistent geological exploration and resource extraction in the Montana interior.

Remote trails and mountain passes, including the Highline route, connect these high-elevation sites. The map documents numerous prospects and adits, such as the Brewster Adit, tucked away in drainages like Golden Gulch and Mason Gulch. This 1989 provisional edition captures the topography of the Sapphire Mountains before modern development, marking significant hydrological features like Mountain Spring and the headwaters of Upper Willow Creek.
