About this map

Petersburg anchors this rural landscape along the border of Delaware and Dubuque counties, where the high prairie of eastern Iowa is etched by a dense network of watercourses. The local topography is defined by the headwaters and drainages of the Little Turkey River in the north and the N Fork Maquoketa River to the southeast. These waterways, including Bear Cr and Elk Cr, create a rolling terrain that breaks the strict agricultural grid of the township system.

For genealogists and local historians, several landmarks provide critical points of reference. The Saint Peter and Paul Cem serves the immediate Petersburg community, while the Saint Patrick Cem and Platt Cem are located further afield among the farmsteads. The northeastern corner of the map reveals more complex elevation changes at Point Hollow, illustrating the transition from open fields to the wooded drainages that characterize this portion of the Driftless Area outskirts.
