About this map

The eastern slopes of Mount Adams are defined here by a dramatic transition from glacial ice to volcanic debris and alpine meadows. The Yakima Indian Reservation covers the eastern half of the map, separated from the Gifford Pinchot National Forest and the Mount Adams Wilderness by the historic Pecore Line (1920-22) and Campbell Line (1906). These survey lines track across a landscape carved by the Klickitat Glacier and Mazama Glacier, which feed into high-elevation water bodies like Bird Lake and Mirror Lake.

High-altitude recreation is evident in the presence of several primitive sites, including Sunrise Camp, Camp (Island Spring), and the Timberline Campground. Geologic history is prominently displayed through the massive A G Aiken Lava Bed and the jagged formations of Battlement Ridge and Victory Ridge. The map also captures several pack trails, such as the High-Line Trail (Pack), which provided essential access through the Bird Creek Meadows and Hellroaring Meadow before modern road networks were established.
