About this map

Agnes Mtn and the surrounding high alpine landscape dominate this mid-twentieth-century survey of the North Cascades. The map details the drainage patterns of the Agnes Creek watershed, including its primary tributaries like West Fork Agnes Creek and South Fork Agnes Creek. High-elevation features define the area, from the perpetual ice of Chickamin Glacier and Blue Glacier to the sharp relief of Sawtooth Ridge and Needle Peak.

Remote and high-altitude hiking routes are documented, most notably the Pacific Crest National Scenic Trail as it winds through the Glacier Peak Wilderness. This 1963 data, updated in the late 1980s, captures the untouched character of the Wenatchee National Forest before more modern infrastructure changes. The boundary between Chelan and Snohomish counties runs through these peaks, showing how the divide between watersheds served as a natural political line in this inaccessible terrain.
