About this map

The Tatoosh Range dominates this landscape, serving as a boundary between the southern reaches of Mt Rainier National Park and the Gifford Pinchot National Forest. This 1989 survey details a high-elevation wilderness where the Unicorn Glacier rests beneath Unicorn Peak and Stevens Peak. The terrain is defined by its drainage systems, with Butter Creek and the Muddy Fork Cowlitz River carving through the slopes.

Lower elevations in the south reveal the small settlement of High Valley tucked along the banks of the Cowlitz River. The map captures the transition from alpine features like Tatoosh Lakes and Blue Lake to the managed timberlands of the Shoqualmie National Forest. Hikers and researchers can identify specific landmarks such as the Hinkle Tinkle Shelter and find the location of a Borrow Pit, indicating the localized human impact on this largely protected environment.
