1971 Map of Erickson Knoll

About this map

The Sheeprock Mountains dominate this high-altitude landscape on the border of Tooele Co and Juab Co, where historical mining activity is etched into the steep drainages. In the early 1970s, the area remained a landscape of remote resource extraction and high-country ranching, centered around peaks like Black Crook Peak and the namesake Erickson Knoll. Small-scale mining operations and prospects are scattered through the eastern canyons, including the Flying Dutchman Mine, Utah Mine, and Copper Jack Mine, reflecting a persistent search for minerals along the mountain flanks. Isolated outposts such as Wright Ranch, Ekker Ranch, and Black Ranch mark the few points of habitation, connected by a network of primitive trails and jeep roads. Much of the terrain is protected within the Wasatch National Forest, preserving groves like Upper Pine Grove and Lower Pine Grove amidst the complex system of washes, including Erickson Creek and Oak Brush Wash.
