The Canada / United States of America international border defines the southern extent of this 2014 survey. This particular quadrangle captures the transition from Whatcom Co in Washington state into the southern reaches of British Columbia, Canada. The landscape is dominated by a complex network of unnamed mountain drainages and headwaters, typical of the high-elevation terrain found along this remote stretch of the 49th parallel. While the map is sparse in terms of named cultural landmarks or settlements, it provides a precise modern look at the hydrological patterns and the geopolitical dividing line between the two nations as it existed in the early 21st century.
