The international border between Canada / United States of America defines this high-latitude survey, where the northern edge of Okanogan Co, Washington meets the British Columbia frontier. This 2014 edition focuses on the complex hydrography and undeveloped terrain along the 49th parallel. While the landscape is characterized by a dense network of unnamed streams and drainages, the primary historical significance lies in the precisely charted boundary line. As a modern digital product from the U.S. Geological Survey, the map provides a clean look at the natural hydrology and official borders of this remote cross-border region before newer forest service updates or land-use changes.
