2018 Map of Blackhawk

About this map

Mississippi River backwaters and agricultural uplands converge along this borderland between Illinois and Iowa. Small riverfront settlements like Lainsville and Marcus sit near a complex network of named islands and sloughs, including Big Soup Bone Island and Lainsville Slough. The inland landscape is defined by the high ground of Heer Hill and several local family-named cemeteries that speak to the area's rural genealogy, such as Morrison Cem, Massbach Cem, and Mosquito Hill Cem. In the northwest, the map documents the Army Depot Rd area near the settlement of Blackhawk, reflecting the long-standing military presence in the region. The drainage of Rush Cr and Little Rush Cr carves through the terrain, connecting upland farms to the expansive wetlands of Savanna Bay and W Hickory Lake.
