About this map

Dyer Mines and several open pit mining operations define the high-altitude industrial character of this portion of the Ashley National Forest. Located near the summit of Dyer Mountain, these sites sit amidst a complex network of canyons and hollows, including Davis Hollow and Kane Hollow. Evidence of earlier activity is recorded at the Bullionville (Site), while the presence of the Military Reservation Boundary suggests the strategic importance of this high-country terrain.

Water management and natural drainage are central to the landscape, from the Oaks Park Reservoir in the northwest to the dramatic Brush Creek Gorge in the southeast. Numerous springs such as Iron Spring and Shelmadine Spring punctuate the slopes, supporting isolated outposts like Iron Spring Camp and the Cotton Ranger Sta. The map also traces the Government Trail and the passage of Big Brush Creek, which carved the deep limestone features of Brush Creek Cave.
