1981 Map of Grider Valley

About this map

Klamath National Forest dominates this section of the Siskiyou Mountains, where high-altitude ridges and deep river canyons define the landscape. The Pacific Crest National Scenic Trail winds through the northern portion of the Marble Mountain Wilderness, providing a primary artery for movement through this undeveloped terrain. This 1981 survey documents a wilderness area largely untouched by permanent settlement, focused instead on natural water sources and land management infrastructure like Lake Mtn Lookout.
