About this map

Trinity Dam and its massive Fixed Crest Spillway dominate this late-twentieth-century landscape, where the waters of the Whiskeytown-Shasta-Trinity National Recreation Area have reshaped the terrain. The map captures a complex overlay of modern recreation and older resource extraction, with the Ridgeville site standing as a silent marker of earlier settlement near the Ridgeville Islands. To the south, industrial and institutional presence is noted at the Powerplant and the Trinity River Conservation Camp.

Resource history is etched into the gulches and ridges through numerous workings such as the Hydraulic Mine, Buckeye Mine, and Little Elsie Mine. These gold-era traces sit alongside modern facilities like the Forest Service Heli Tack Complex and Pine Cove Mobile Home Park and Marina. The extensive network of boat ramps and campgrounds, from Stuart Fork to Hayward Flat, illustrates the area's transition into a major regional hub for water-based recreation.
