The mountain-mining economy of Granite County is etched across this 2011 survey, centered on the settlement of Maxville and the high-altitude topography of Mount Princeton. The landscape is dominated by the complex drainage systems of Boulder Creek, Flint Creek, and Gird Creek, which served as the lifelines for over a dozen named mining operations. Industrial history is evident in the cluster of sites near Princeton, including the Princeton Placer Mine and Travonia Mine, illustrating a legacy of extraction that spans phosphate and metal mining. Many of these sites, such as the Londonderry Mine and Royal Basin Mine, are situated at significant elevations along steep gulches like Wyman Gulch. This map records a rugged section of the northern Rockies where primitive access roads like Gird CR RD and Maxville RD connect scattered workings, such as the Cominco Phosphate Mine and the distant Gold Reef, to the valley floor.
