1950 Map of Dyer Mountain

About this map

Dyer Mines and several other open pit excavations dot the high elevations of Dyer Mountain in this mid-century survey of the Ashley National Forest. The landscape is a complex network of high-country drainage, with Brush Creek and Little Brush Creek carving deep into the terrain to form the dramatic Big Brush Gorge. Evidence of early 20th-century activity is preserved at the Bullionville (Site), while the Colton Ranger Sta and Iron Spring Camp suggest the area's continued use for forest management and seasonal occupancy. The map detail highlights the intersection of resource extraction and water management, visible in the Government Ditch and natural landmarks like Brush Creek Cave. From the Colton Canyon Overlook to the remote Oaks Park Reservoir, the topography shows a region defined by its industrial history and the rugged character of the Uinta Mountains.
