High-altitude hydrology and the international boundary line define this 2017 survey of the northern Cascades. Centered on the remote border between Washington and British Columbia, the landscape is dominated by a complex network of glacial meltwater streams and seasonal drainages. The primary administrative feature is the sovereign border of Canada, which runs along the bottom edge of the quadrangle. Given the lack of human infrastructure or named settlements on this specific sheet, the map serves as a detailed record of the pristine drainage basins and natural terrain at the headwaters of the Fraser Valley region just before the close of the decade.
