About this map

Mt Hood National Forest dominates this 1990s terrain, where the headwaters of the Salmon River and Roaring River carve through the northern Cascades. The map details a landscape managed for both timber and recreation, centered on prominent peaks like High Rock and Frazier Mtn. Industrial history is etched into the topography through scattered operations such as the High Rock Quarry, Sink Quarry, and Round Wolf Pit.

Water is a defining feature of the quadrangle, which includes the Salmon - Huckleberry Wilderness and numerous named cascades like Little Niagara Falls and Frustration Falls. Within the Rock Lakes Basin, several alpine lakes are identified, while forest access is marked by points like the Frazier Turnaround and various lookout sites. This survey documents the network of trails and secondary roads that served Clackamas County’s remote high country at the close of the twentieth century.
