About this map

Belleview and Henden townships reveal a landscape of glaciated plains and marshy depressions in the late 1960s. The agricultural grid is punctuated by numerous sloughs and small lakes, including McCart Slough, Silver Lake, and the curiously shaped The Horseshoe. Local community life is anchored at the Belleview Ch and the Townhall, reflecting a period when small rural townships maintained distinct civic identities. The Chicago Milwaukee St Paul and Pacific railroad cuts across the southern portion of the sheet near the Little Vermillion River, serving the region's transport needs alongside an underground pipeline. Large tracts of land are dedicated to the National Wildlife Management Area, preserving the prairie potholes and wetland habitat essential for migratory birds in this portion of South Dakota.
