About this map

Glacial depressions and seasonal wetlands define the prairie landscape of Adams Township in the early 21st century. The drainage pattern is anchored by the E Fork Vermillion River in the northeast and the Little Vermillion River to the south. Numerous named sloughs and lakes, such as McCart Slough, Wombacker Slough, and Otter Lake, dot the grid-patterned terrain, reflecting the high water table characteristic of this part of Miner County. The surveyor’s grid is strikingly regular here, with numbered roads like 225th St and 436th Ave marking the township lines and section boundaries. This 2012 record captures the area's agricultural layout, where the natural hydrology of features like The Horseshoe and Silver Lake still dictates the placement of fields and rural homesteads amidst the expansive South Dakota plains.
