1986 Map of Mount Callaghan

About this map

The high ridges of the Toiyabe Range dominate this mid-1980s landscape in Lander County, anchored by the prominent summit of Mount Callaghan. The map records a rugged environment shaped by water and mineral exploration, with numerous prospects and prospect pits scattered across the steep drainages of Charlie Canyon and Callaghan Canyon. Human activity is concentrated along the lower elevations where the Callaghan Ranch sits near the confluence of local forks. Water sources are critical identifiers here, from the headwaters of Boone Creek and Skull Creek to the seasonal flow of Cottonwood Spr and Ox Corral Creek. A notable Pipeline and a network of unimproved roads suggest the ongoing utility of this high-desert terrain for ranching and resource surveying during the late twentieth century.
