About this map

The S Fork Salmon River carves through the Salmon Mountains in this high-altitude region of the Klamath National Forest and Trinity National Forest. The landscape is defined by its drainage systems and steep ridgelines, where the Siskiyou Co and Trinity Co line meets at significant elevations. Human history in these peaks is marked by the eponymous Summerville and the curiously named Schoolhouse Flat, suggesting early mountain settlements or seasonal clearings.

Water is a dominant feature, with glacial remnants like Grizzly Lake, Lois Lake, and Emerald Lake dotting the Trinity Alps. These alpine basins are connected by a network of historic paths, including the Blind Horse Trl and McNeil Creek Trl. The map also details mining and prospecting history through features like Yellow Jacket Basin and various named gulches, providing a look at the land use and accessibility of the Coast Ranges during the early 21st century.
