1954 Map of Blackrock Mtn

USGS Topo · Published 1963

About this map

Trinity National Forest and Six Rivers National Forest define this mid-century landscape where high ridges and river forks meet. The terrain is marked by a network of seasonal camps and remote outpost ruins, including Double Cabins and Blossom Cabin, reflecting the area's history of forest management and transient residency. Resource extraction is evident through several mining sites like the Bonanza Mine and Blujay Mine tucked into the steep slopes of the South Fork Trinity River and Mad River watersheds. The mapping reveals a transition into the Mendocino National Forest, with the Indian Dick Guard Station serving as a key administrative anchor in the south. The presence of sites like Travis Ranch and Police Camp alongside rugged features like Black Rock Mountain illustrates a period of isolated mountain living and early backcountry recreation before more modern road systems were established.
