The Turtle Mountains dominate this landscape on the international border between North Dakota and Canada. This plateau region is characterized by a high density of water bodies, including the irregular shores of Lake Upsilon, Belcourt Lake, and Gravel Lake. The distribution of these lakes, such as School Section Lake and the Cool Lakes, suggests a post-glacial terrain where natural drainage is fragmented into numerous basins.
