2015 Map of Blackhawk
USGS Topo · Published 2015About this map
The Mississippi River forms the central character of this 2015 survey, defining the border between Carroll County and Jackson County, Iowa. The river's complex backwaters and side channels create a maze of landforms, including Big Soup Bone Island, Little Soup Bone Island, and Railroad Island. Inland, the terrain rises sharply into the bluffs of Derinda Township, where Heer Hill and several local family burial grounds like Morrison Cem and Albright Cem overlook the valley.
