About this map

Six Rivers National Forest, Trinity National Forest, and Mendocino National Forest converge in this high-altitude landscape where the Mad River and Trinity River carve through complex ridges. The map reveals a network of remote outposts and resource extraction sites, including the Bonanza Mine near Van Horn Peak and the Lucky Sunday Mine to the southwest. These names hint at the mid-century persistence of mining and ranching interests in a region dominated by public lands and the Yolla Bolly wilderness.

Scattered cabins and camps suggest a rugged seasonal economy and forest management infrastructure. From the ruins of Blossom Cabin and Jensen Cabin to operational sites like Indian Dick Guard Station, the map documents the human footprint in the backcountry. Notable landmarks like Tombstone Rock and the many glades along Trinity Ridge provide essential navigation points for those traversing the Humboldt Trail or crossing the river at Hoxie Crossing.
