2020 Map of Froelich Dam

About this map

Froelich Dam serves as the central landmark in this part of Sioux County, where the plains of the Fort Yates District meet the rising topography of the Porcupine Hills. The landscape is defined by the drainage of Porcupine Cr, which meanders through the south and west portions of the quadrangle. This 2020 record captures the rural infrastructure of the Standing Rock Reservation, tracing the paths of Bia Rd 7 and Bia Rte 7 as they traverse the open country. To the southwest, the terrain levels into the Little Heart Flats, a distinct contrast to the more complex relief found to the east. The map provides a clear look at the township and range divisions, including t132n r82w and t131n r82w, which ground the area's modern land management in its historical survey roots.
