About this map

Briggs Ranch sits along the western edge of this mid-1960s survey, marking a centered point of habitation in a landscape defined by dramatic elevation changes and drainage basins. The Red Rock River winds through the valley floor, accompanied by the prominent line of the Union Pacific railroad and a nearby Landing Strip. This transportation corridor is vital to the area's connectivity, serving the remote ranchlands of Beaverhead County.

The rugged eastern terrain is carved by complex systems like Ashbough Canyon and Little Ashbough Canyon, where water sources like Ashbough Spring and Knox Spring provide critical resources. The presence of a Gaging Sta on the river suggests the importance of water management and monitoring for the surrounding agricultural interests during this era. High-altitude features like The Basin and several steep gulches emphasize the isolated, vertical nature of the Montana backcountry.
