The international border between Canada and the United States of America defines the northern edge of this North Cascades terrain in Whatcom County. As a modern 2023 survey, the map illustrates the precise boundary line where Washington meets British Columbia, primarily tracking the wilderness and public land survey system lines of T41n R5e and T41n R6e. The landscape is characterized by its high-elevation drainage patterns and the administrative division of the 49th parallel, providing a detailed record of the border's physical geography and modern road network at the edge of the Pacific Northwest.
