2017 Map of Twin Sisters Mountain
USGS Topo · Published 2017About this map
Twin Sisters Mountain dominates this portion of the Mount Baker National Forest, where the high peaks of the Twin Sisters Range create a formidable divide between the watersheds of the Middle Fork Nooksack River and the South Fork Nooksack River. The terrain is characterized by sharp elevations such as North Twin and South Twin, connected by the high-altitude Sister Divide. These peaks provide a natural barrier that has historically dictated the movement of travel and water through the region.
