Slade National Wildlife Refuge anchors this section of the Prairie Pothole Region, protecting a complex of glacial water bodies including Upper Harker Lake, Harker Lake, and Lake Isabel. The landscape is defined by these shallow basins and the section-line road grid that organizes the surrounding agricultural plains. Local history is preserved at the Dawson Cem and Koestler Cem, which serve as quiet markers of the early families who settled these townships. In the northern corner, the outskirts of Tappen sit along the rail corridor, while the southern reaches are dedicated to conservation through the Kidder County Waterfowl Production Area. This 2024 survey illustrates the ongoing balance between the region's waterfowl habitat and the persistent grid of rural infrastructure like 38th St SE and 35th Ave SE.
