2017 Map of Boundary Mountain OE N

About this map

The United States of America/Canada international boundary defines the lower edge of this 2017 survey, where Washington State meets British Columbia. This high-latitude landscape is dominated by a complex network of unnamed northern waterways and drainages that flow through the borderlands. Mapping by the U.S. Geological Survey and agencies like the BLM and FWS captures a sparse, high-country wilderness where the primary human-made feature is the geopolitical line itself. The map reveals the intricate hydrography of the region just north of the border, providing a clear look at the drainage patterns and terrain before they cross into the United States.
