About this map

Mount Deception and Mount Constance dominate this high-elevation landscape within the Olympic National Park and surrounding wilderness areas. The map reveals a complex network of alpine hydrology, where headwaters like the Dosewallips River and Dungeness River originate from glacially carved features such as Deception Basin and Royal Basin. The terrain is characterized by sharp ridgelines like Gray Wolf Ridge and notable summits including Mount Mystery and Mount Fricaba.

For backcountry researchers and historians of the Olympic Peninsula, the map documents established routes like the Pacific Northwest National Scenic Trail and the Royal Basin Trail. These paths connect remote water bodies such as Royal Lake, Home Lake, and Lake Constance. The inclusion of high-mountain passes like Marmot Pass and Constance Pass illustrates the historical corridors used to navigate this formidable interior.
