About this map

Old Snowy Mountain and the high ridges of the Cascades define this high-elevation landscape in Yakima County. The terrain is characterized by significant glacial features, including the Packwood Glacier and McCall Glacier, which feed the headwaters of the Clear Fork Cowlitz River and the North Fork Tieton River. Historical backcountry navigation is marked by a series of high-altitude crossings such as Tieton Pass, Elk Pass, and the Packwood Saddle.

Evidence of recreational infrastructure is noted at the Dana Yelverton Shelter, situated near the glaciers. The map details a complex hydrologic system where drainage from peaks like Ives Peak and Hawkeye Point collects into alpine basins and lakes, including Goat Lake and Coyote Lake. The naming conventions throughout the quadrangle, from Hogback Mountain to Egg Butte, reflect a long history of local geographic identification in this wilderness area.
