Trinity Alps and the high ridges of the Salmon Mountains define this landscape along the border of Siskiyou and Trinity Counties. The terrain is marked by a high density of alpine basins and glacially carved features, including Caribou Lake, Snowslide Lake, and Emerald Lake situated below the sharp crest of Sawtooth Ridge. Traces of the region's mining and grazing history appear in names like Big Flat and Browns Meadow, while the Dorleska Mine Trl provides a physical link to former mineral extraction sites. Water from these heights feeds into the South Fork Salmon River and the Stuart Fork, creating a complex network of canyons such as Crosby Gulch and Petrified Gulch. The map's extensive trail system, including the Tri-Forest Trl and Old Caribou Trl, reflects the area's modern role as a protected wilderness managed by the Shasta, Klamath, and Trinity National Forests.
