2017 Map of Ruby Dam

About this map

Ruby Dam stands at the northwestern edge of this landscape, holding back the Ruby River Reservoir as the Ruby River flows north through Madison County. The terrain is defined by a series of steep drainages including Davey Cr, Idaho Cr, and Jack Cr, which cut through the high country of the Beaverhead National Forest. This 2017 survey captures a remote ranching and forest environment where access is maintained via unpaved routes like Upper Ruby Rd and Barton Gulch Rd. Local landmarks like Metzel Ranch and the small settlement at Barton Gulch reflect the sparse human imprint on these highlands. From the depths of Dark Hollow to the upper reaches of N Fork Greenhorn Cr, the map illustrates a network of seasonal streams and ridgelines that characterize this portion of southwestern Montana.
