1961 Map of Ashbough Canyon

USGS Topo · Published 1965

About this map

The Blacktail Mountains dominate the southwestern portion of this map, dropping sharply toward the winding valley of Blacktail Deer Creek. The landscape is defined by its ranching heritage, with several family-named outposts such as Rock Island Ranch and Landon Ranch scattered across the lower elevations. The intricate drainage network of the mountains is revealed through narrow cuts like Ashbough Canyon and Weston Canyon, which feed into the primary creek. A significant change in terrain is visible between the steep, forested slopes and the wide, open ranch lands to the north and east, illustrating how the geography dictated early settlement and land use. Small industrial indicators, including Borrow Pits, appear near the mountain base, while natural landmarks like Irishmans Hole suggest localized points of interest in an otherwise sparse, working landscape.
