1950 Map of Slide Peak

About this map

Soleduck River and the Bogachiel River define this high-altitude landscape along the border of Clallam and Jefferson counties. Originally mapped in the 1940s and 1950s, the terrain represents a transition between the Olympic National Forest and Olympic National Park. The topography is dominated by steep ridges and peaks such as Slide Peak, Misery Peak, and the distinctively named Sore Thumb. The map reveals the early foot-travel infrastructure of the backcountry, highlighting remote outposts like Hyak Shelter and Twentyone mile Shelter. These locations, along with the Low Divide, mark significant points for researchers tracing old trail routes and early wilderness management. Hidden within the high basins are isolated water bodies like Ring Lake and Blackwood Lake, which feed the complex network of tributaries including Hyak Creek and Alckee Creek.
