2017 Map of Hickman Lake

About this map

The Coteau des Prairies plateau dominates this section of Marshall County, creating a distinctive landscape of glacial deposits and numerous small prairie potholes. This high ground is punctuated by Hickman Lake in the southwestern portion of the map, a characteristic example of the water bodies that dot this upland region. The topography is defined by the underlying township and range system, with Co Hwy 12 and Co Hwy 20 providing the primary east-west corridors through the rural township divisions. The grid-like road network, including numerous numbered avenues and streets like 113th St and 425th Ave, reflects the systematic agricultural settlement of this northern South Dakota landscape. This map documents the persistent rural character of the region, where the intersection of natural glacial features and precise human-imposed boundaries remains the defining structural element.
