Silver La Donna Mine and the Anderson Mine sit at the southern end of this mountainous Powell County landscape, where the headwaters of Brock Creek and its tributaries carve through the terrain. This 2011 survey captures a region defined by high-elevation landmarks such as Old Baldy Mountain and the White Rocks Mountain in the southeast corner. The extraction history of the area is evident through several named mining sites, including the Relyea Mine and the NE NW Section 7 Mine, which are accessed by limited infrastructure like Brock Creek Rd.
