1982 Map of Thurston Peaks

About this map

Salmon Trinity Alps Primitive Area defines the character of this 1982 provisional survey, showcasing a landscape largely untouched by modern development. The map focuses on the steep drainages within the Trinity National Forest, where the North Fork Trinity River and the South Fork East Fork New River carve through the high country. Numerous established campsites and mountain shelters, such as Strunce Cabin and Ladder Camp, suggest a long-standing culture of seasonal occupancy and backcountry access. This particular edition captures the area's transition into more formal wilderness management, marking several locations as sites rather than active structures, including Rattlesnake Camp (Site) and Bear Wallow Camp (Site). The terrain is punctuated by distinctive geological features like Limestone Ridge and Pony Mountain, connected by a network of paths including a designated Pack Trail near the northern boundary.
