1963 Map of Agnes Mtn.

About this map

The Glacier Peak Wilderness dominates this high-elevation landscape on the border of Chelan and Snohomish counties, showing a region defined by active ice and vertical relief. Glacial features like Blue Glacier, Chickamin Glacier, and Dark Glacier are mapped in detail across the slopes of prominent summits such as Agnes Mtn, Needle Peak, and Mount Blankenship. The central drainage of Agnes Creek and its tributaries, including South Fork Agnes Creek and West Fork Agnes Creek, provide the primary topographical structure for the area. The Pacific Crest National Scenic Trail traverses the eastern half of the map, following the contours of the high country between Lyall Ridge and the Seven Sisters. This 1963 survey, updated in the late 1980s, documents the permanent ice fields and alpine water bodies like the Bannock Lakes before significant modern glacial recession.
