About this map

Goat Rocks Wilderness dominates this 1988 survey, straddling the high-elevation boundary of Lewis and Yakima counties. The landscape is defined by the sharp transition between the Gifford Pinchot and Snoqualmie National Forests, centered on the volcanic remnants of Old Snowy Mountain. Significant glacial activity is recorded through the presence of Packwood Glacier and the Mc Call Glacier, which feed the headwaters of the Cowlitz River and the North Fork Tieton River.

For hikers and historians of the trail system, the Pacific Crest National Scenic Trail is mapped in detail as it winds along the spine of Hogback Ridge. High-altitude basins like McCall Basin and alpine water bodies such as Coyote Lake and Shoe Lake punctuate the ridges, while named crossings like Packwood Saddle, Tieton Pass, and Elk Pass provide the primary transit points through this glaciated terrain.
