1989 Map of Blackbird Creek

USGS Topo · Published 1989

About this map

Blackbird Mine anchors the northern drainage of this section of the Salmon National Forest, where steep drainages and ridge systems define the geography of the late 1980s. The landscape is marked by industrial and service outposts like the Cobalt F S Sta and the Cobalt Heliport, signaling the active management and extraction history of the area. A network of prospects, adits, and tailings sites are concentrated along Blackbird Creek and its tributaries, while the former settlement at Forney (Site) sits at the southern edge near Sawmill Gulch. The map records a complex terrain of named ridges such as Porphyry Ridge and Trans Line Ridge, which separate the various creek systems including Panther Creek and Musgrove Creek. Recreational and communication infrastructure is also present, from the McDonald Flat Campground to a Radio Tower overlooking the Musgrove Mine.
