About this map

The high Cascades along the boundary of Lewis and Yakima counties center on the formidable Goat Rocks massif. This recent survey captures the complex alpine environment where the McCall Glacier and Packwood Glacier cling to the slopes of Old Snowy Mtn and Ives Peak. The landscape is defined by its verticality, from the depths of the Clear Fork Cowlitz River valley to the heights of Johnson Peak and Tieton Peak.

Transit through this protected wilderness is documented via the Pacific Crest National Scenic Trail, which winds past high-elevation landmarks like Tieton Pass and Hogback Mtn. The map detail shows the headwaters of several major drainages, including the N Fork Tieton River and Coyote Cr, illustrating the glacial hydrology that feeds the surrounding Gifford Pinchot and Snoqualmie national forests.
