About this map

Trinity Alps Wilderness dominates this late-twentieth-century survey, showcasing a landscape defined by high-elevation lakes and the intricate headwaters of the Trinity River. The region reflects a legacy of both resource extraction and backcountry recreation, anchored by the Grand National Mine and the isolated Messner Cabin. Alpine basins cradling Tangle Blue Lake, Big Bear Lake, and the smaller Wee Bear Lake are linked by rugged footpaths, including the Pacific Crest National Scenic Trail and the Bear Creek Trail.

Along the eastern edge, the terrain descends toward the Trinity River corridor, where working landscapes like Trumble Ranch and Eagle Creek Ranch sit near developed recreation sites such as Horse Flat Campground. This map captures the intersection of designated wilderness and managed forest lands, recording the trailheads and ranger districts that facilitate access to the high granite peaks and timbered drainages of the Shasta-Trinity National Forest.
