2021 Map of Irish Creek NE

About this map

Firesteel Creek meanders through this portion of the northern Great Plains, cutting a winding path across the boundary between Corson and Ziebach counties. The landscape is defined by its drainage systems, including the headwaters of Red Earth Creek and the northward flow of Cottonwood Creek. This 2021 survey reflects the enduring section-line grid of the Public Land Survey System, revealing how the geography of South Dakota remains anchored to the legal townships of t17n r21e and t18n r21e. While the map is notably sparse of modern settlements, the topographic contours and watercourses provide a detailed look at the unpopulated prairie as it appeared in the early 21st century.
