About this map

The Hamma Hamma River carves a deep path through this mid-1980s terrain where the Jefferson and Mason county line meets the high ridges of the Olympic Peninsula. The landscape is dominated by the transition between the Olympic National Park and Olympic National Forest, anchored by the massive presence of Mt Washington. A network of glacial lakes including Lena Lake, Jefferson Lake, and Tenas Lake dots the drainage basins, illustrating the complex hydrology of the watershed.

Evidence of human activity is concentrated in pockets such as the Lena Creek Campground and scattered infrastructure like the Gravel Pit and Borrow Pit near the eastern margin. Historical pathways are traced through Washington Pass and along Jefferson Ridge, offering a clear view of the mountain topography before more modern developments. This survey captures a specific era of forest management and alpine recreation, centered on the heights of Jefferson Peak and Mt Bretherton.
