The Coeur d'Alene Mountains dominate this late-twentieth-century landscape, where the CC Divide forms a high-elevation boundary between Sanders and Mineral Counties. The area is defined by the steep drainage basins of the St Regis River, where the small settlement of De Borgia sits at the southern edge of the quadrangle. This map captures a legacy of hard-rock mining tucked into the forested ridges of the Lolo National Forest, with several named operations including the Copper Rock Mine, Texas Mine, and Valentine Mine scattered across the rugged terrain.
