2017 Map of Martin SW

About this map

The prairie landscape of t36n r37w and t36n r38w in Bennett County reveals a sparse but distinct hydrographic network within the Sand Hills region. The upper reaches of Lake Cr dominate the northern and central sections, weaving through a complex series of seasonal wetlands and small depressions characteristic of this high-plains environment. This 2017 study illustrates the delicate drainage patterns that define the South Dakota ranchlands, where the land is organized according to the Public Land Survey System boundaries of t35n r37w and t35n r38w. To the east, the headwaters of Cedar Cr emerge, cutting through the terrain and providing critical water resources for the isolated homesteads and agricultural operations that rely on these intermittent seasonal flows.
