Silvertip Mtn and the high ridges of the Northern Rockies define this 1930s landscape, where remote outpost management and aviation infrastructure were critical for backcountry access. The survey highlights a network of administrative sites such as the Black Bear Guard Sta and Big Prairie Ranger Sta, supported by a series of primitive airfields including the Meadow Creek Landing Field and Bartlett Landing Field. This reliance on remote landing strips alongside traditional pack trails like the Continental Divide Trail illustrates the mid-century transition in wilderness logistics.
