About this map

The Glacier Peak Wilderness defines the high-altitude character of this mid-1960s survey, where the boundaries of the Mt Baker National Forest, Snoqualmie National Forest, and Wenatchee National Forest converge. The landscape is dominated by a complex network of ridgelines and peaks, including the prominent Bench Mark Mtn and the striking Vimy Ridge. The absence of roads is notable, as the region is navigated exclusively by a system of historical pack trails.

Water features are abundant in these high basins, from the North Fork Sauk River to isolated alpine pools like Lake Sally Ann, Blue Lake, and Pear Lake. The map reveals the intricate drainage patterns of Cady Creek and the North Fork Skykomish River, which flow from critical transit points such as Dishpan Gap and Cady Pass. For the researcher, the map preserves the exact alignment of these high-country routes before the modern era of wilderness management changed the usage of these primitive pack trails.
