Jefferson City and the nearby community of Corbin serve as the primary focal points for this 2017 survey of the Montana landscape. Located within the drainage of Prickly Pear Cr, these settlements are situated in a terrain defined by steep gulches and high peaks, including Wolf Mtn and Emerson Peak. The northern reaches are heavily influenced by the Helena National Forest, where a dense network of mountain roads such as Lump Gulch Rd and Sheep Mountain Rd thread through the hills. This map illustrates the intersection of small-town infrastructure and rugged timberland, showing how local landmarks like McCauley Flats and various spring systems, including Mudd Springs, are integrated into the geography. To the east, Clancy sits along the Hwy 282 corridor, marking the easternmost extent of this detailed topographical study.
