1960 Map of Boyd Ridge

About this map

Bighorn National Forest dominates this high-altitude landscape along the border of Big Horn and Sheridan Counties. The terrain is defined by the sharp elevations of Boyd Ridge and Crater Ridge, where deep drainages like Mann Creek and Wagon Box Creek cut through the timbered slopes. Industrial activity is represented by the Marble Quarry located in the northern reaches, accessed by the rugged Marble Quarry Road. This area, surveyed for the Department of the Interior's Missouri River Basin development program, shows a wilderness primarily used for natural resource extraction and watershed management. Local landmarks like Sheep Mtn and the isolated Crater Spring provide reference points for those tracking historical land use and early access routes through the northern Bighorn range.
