1999 Map of Mount Olson

About this map

Mount Olson and Wonder Mountain anchor a landscape defined by dramatic elevation changes and a dense network of numbered drainage systems. This 1990s revision by the USDA Forest Service highlights the protected status of the high country, where the Wonder Mountain Wilderness meets the southern boundary of Olympic National Park. The survey illustrates the watershed divide separating the Quinault River in the northwest from the headwaters of the North Fork Skokomish River to the south. Alpine features like Lake Success and McGraws Lakes are reached only by a Primitive Trail crossing Six Ridge, reflecting the area's isolation. Significant streams—including Seven Stream, Six Stream, and Five Stream—carve deeply through the terrain, illustrating the complex hydrology of the Olympic Peninsula's interior wilderness.
