2011 Map of Boreas Pass

About this map

SallyBarber Mine and a dense cluster of high-altitude mining claims define the western slopes of the Tenmile Range in this 2011 survey. The landscape is a complex network of 19th-century industrial remnants and modern forest access, where historic sites like the Corporal Mine and Tommy Mine sit near established mountain routes like Boreas Pass Rd. To the southeast, the terrain shifts from heavy mining to early ranching and settlement sites, including the Schattinger Homestead, Volz Homestead, and Liesburg Homestead along the drainage of Mountain Creek. This transition from the extraction economy near Lincoln to the more isolated homesteads near Antelope Gulch reflects the varied ways the high country was settled. Notable water management features, such as Boreas Ditch Number 2 and the Upper Michigan Reservoir, highlight the critical role of water diversion in this arid alpine environment.
