This mountainous expanse near the international border is defined by a complex network of streams and drainages flowing through the high country. Situated just north of the United States, the terrain is dominated by the natural hydrography that feeds into the regional valley systems. The primary marker on this landscape is the international boundary of Canada, which delineates the northern edge of the survey area. Researchers can observe the intricate patterns of natural water flow across the topography, illustrating the watershed's character before it reaches more developed settlements to the south. This 2020 dataset reflects the modern state of the wilderness, focused on the physical geography of the British Columbia interior.
