About this map

Summerville stands along the South Fork Salmon River, a remote settlement in the high country where the Klamath National Forest meets the Trinity National Forest. This 1970s survey captures the intersection of early pioneer industry and protected wilderness, showing the Moliter Mine and several mines tucked into the gulches. Historically significant sites like Schoolhouse Flat and Bobs Farm suggest a landscape of early homesteading and resource extraction that preceded the area's designation as the Salmon Trinity Alps Primitive Area.

The terrain is defined by the sharp peaks of the Salmon Trinity Alps Mountains, including Thompson Peak and Caesar Peak. Hikers and researchers can trace a network of pack trails, such as the Boardtree Trail and Rush Creek Trail, which connect isolated features like Grizzly Lake and Lois Lake. Small cemeteries, noted simply as Cem, and isolated graves along the trails provide tangible links to the individuals who lived and worked in these high elevations.
