2017 Map of Lake Upsilon SE

About this map

The Turtle Mountains provide a distinct rolling landscape in this portion of Rolette County, characterized by a dense network of glacial wetlands and small basins including Marion Lakes and Belcourt Lake. The settlement of Belcourt occupies the northeastern section, showing a detailed street layout near the Saint Anns Addition Cem, while the community of Shell Valley is situated further south along the junction of 281 and Old Hwy 5. Local genealogy and land use are anchored by sites such as the White Stone Cem and an extensive grid of Bureau of Indian Affairs routes like Bia RD 6 and Bia RD 21. This 2017 survey details a landscape where water management and tribal infrastructure are central, with several branches of Wolf Cr and Ox Cr draining the elevated terrain toward the south and east.
