About this map

The high peaks of the Cascade Range define this northern Washington landscape, situated directly on the international border between the Canada United States line. The map captures a high-elevation environment where Mt Baker Wilderness and North Cascades National Park intersect. Historically significant for its difficult access, the area features the Hannegan Pass Trail winding toward Hannegan Pass, a key corridor through the mountains.

Evidence of early exploration and geological interest is marked by several Prospects and a Tunnel located near the drainage of Ruth Creek. The terrain is characterized by massive summits like Mt Sefrit and Goat Mtn, with the N Fk Nooksack R and the headwaters of Silesia Creek carving deep drainage patterns through the high country. This document is particularly valuable for tracing the precise boundaries of federal lands as they stood in the late twentieth century.
