1998 Map of Black Rock Mountain

About this map

Martin Cabin and several historic cabin sites anchor this rugged high-altitude landscape where the Shasta-Trinity National Forests meet the Mendocino National Forest. The map documents a transition in wilderness management, showing the Eel River Middle Bolly Yolla Wilderness boundary stretching across prominent landmarks like Black Rock Mtn and its associated lookout. The terrain is defined by the headwaters of the South Fork Trinity River and the North Fk Middle Fk Eel River, revealing the complex drainage systems of the Northern California Coast Ranges. Local history is preserved through labels for remote camps and clearings like Bearwallow Camp and Penney Glades, while the Humboldt Trail and Mad River Road provide the primary historical access through these mountain ridges.
