About this map

Mount Rainier National Park and the Gifford Pinchot National Forest meet in this high-altitude landscape of Lewis County. The terrain is defined by the sharp elevations of the Tatoosh Range, where the Unicorn Glacier feeds drainage into the Muddy Fork Cowlitz River. Glacial and alpine water sources such as the Tatoosh Lakes and Blue Lake dot the high basins, while the lower elevations are carved by Butter Cr and Skate Cr.

In the southern reaches near the Cowlitz River, a small network of roads including Lake Creek Rd and Terrace Way serves the area around Evergreen Cem. The map illustrates the convergence of wild federal lands, with the Snoqualmie National Forest bordering the western edge. Notable peaks like Eagle Peak and Unicorn Peak anchor the ridgelines, providing a clear picture of the hydrological divide between these major river systems in the modern era.
