1961 Map of Ashbough Canyon

USGS Topo · Published 1972

About this map

Blacktail Mountains dominate the southwestern portion of this landscape, rising sharply from the basin formed by Blacktail Deer Creek. The area is characterized by a series of deep canyons and gulches, including Ashbough Canyon, Coyote Canyon, and Van Camp Canyon, which carve through the high ground towards the drainage floor. This 1961 field check shows a predominantly ranch-based economy with family-named operations like Landon Ranch, Conover Ranch, and Rock Island Ranch situated near vital water sources. The presence of Borrow Pits and a Mine suggests small-scale resource extraction alongside the grazing activity. A peculiar landmark, Irishmans Hole, marks the rugged slopes below the main ridgeline, indicating the specialized local nomenclature of the Beaverhead County backcountry.
