About this map

Deerlodge National Forest dominates this section of Granite County, where the hydrology is defined by the northward flow of Rock Creek and its many seasonal tributaries. The terrain is characterized by a dense network of gulches, including Cornish Gulch, Bi-Metalic Gulch, and Puller Gulch, indicating a landscape shaped by historical mining and prospecting activities. High points like Ram Mtn and Wright Rock overlook the drainages, while infrastructure such as the Squaw Rock Airstrip and Bobcat Field suggest specialized land use in this mountainous area.

Transportation through the drainage follows Rock Creek Rd, crossing the Kyle G. Bohrnson Bfc US Army Memorial Bridge as it moves through the canyon. The southern portion of the map features several large private holdings, including W Rocking J Ranch Lane, contrasted with the public land designations of t6n r16w and adjacent townships. This contemporary survey records the intersection of modern ranching, aviation, and forest management within a classically carved Montana landscape.
