About this map

Mt Hood National Forest dominates this mid-1980s topography, revealing a landscape defined by dramatic elevation changes and a complex network of waterfalls. The northern reaches are marked by the Salmon River, where the terrain drops sharply at Frustration Falls, Vanishing Falls, and Final Falls. This map is particularly valuable for recreation historians, as it documents the locations of developed forest sites such as Hambone Spring Campground and the Frazier Turnaround Campground during a period of active timber and land management.

The central and southern portions of the quadrangle are anchored by prominent peaks and ridges, including Signal Buttes, Frazier Mtn, and High Rock. These landmarks overlook deep basins and high-altitude water bodies like Plaza Lake, Salmon Lake, and Shellrock Lake. The drainage patterns of the Roaring River and its numerous tributaries, including Splintercat Creek and Cougar Creek, illustrate the natural hydrologic corridors that shaped the access routes and fire management trails of the era.
