1953 Map of Blackrock Mtn

USGS Topo · Published 1973

About this map

Six Rivers National Forest and Mendocino National Forest converge in this mid-century study of the high Trinity divide. The landscape is defined by the steep drainage basins of the South Fork Trinity River and the multiple forks of the Eel River, which carve through deep ridges and glades. Evidence of early interior travel is preserved in the Humboldt Trail, while several remote outposts like Double Cabins and Blossom Cabin are already noted as ruins by this time.
