1956 Map of Bull Run

About this map

White Rock stands as a notable marker of past activity in this high-altitude landscape where mining and ranching dominated the mid-century economy. The eastern half of the map is largely defined by the Humboldt National Forest, which encompasses significant peaks such as Pennsylvania Hill and Porter Peak. A dense network of mining claims is concentrated in the northern canyons, featuring the Blue Jacket Mine, California Mine, and the Edgemont Mine along Edgemont Creek. These operations, connected by narrow mountain roads and a jeep trail, point to a history of hard-rock extraction.
