1970 Map of East Canyon Ridge

About this map

The Cispus River valley carves through this portion of the Gifford Pinchot National Forest in Skamania County, defined by its network of backcountry trails and high ridges. By the early 1970s, the landscape was managed for recreation and forestry, featuring sites like the Adams Fork Campground and a fire Lookout at Summit Prairie. The topography is dominated by massive features such as East Canyon Ridge and Table Mtn, which separate the various drainages of East Canyon Creek and Quartz Creek. High-elevation water bodies like Blue Lake, Mouse Lake, and Council Lake provide localized points of interest in a terrain otherwise characterized by steep elevation changes and a labyrinth of namesake waterways including Adams Creek and Orr Creek. A detailed network of Pack Trails and the Jeep Trail suggests the era's reliance on primitive access routes for forest management and local exploration.
