Ruth Lake and its impounding Robert W Matthews Dam dominate this late 20th-century landscape in Trinity County. This specialized update, revised by the Forest Service, documents the overlapping boundaries of the Six Rivers National Forest and Trinity National Forest. Beyond the modern reservoir, the map preserves older historical footprints such as the Ueland Place (Site), the Old Wilburn Ranch, and a small Cem in the Hettenshaw Valley. The topography is marked by named openings and clearings in the heavy timber, including Murphy Glades, Boles Opening, and Rainy Glades. These features, alongside drainage patterns for the Mad River and Van Duzen River, illustrate the complex relationship between water management, timber resources, and remote homesteading sites in the Coast Ranges.
