2013 Map of Petersburg

About this map

Petersburg and Holy Cross anchor this Delaware County landscape, characterized by the intricate drainage systems of northeastern Iowa. The north-central section is defined by the Little Turkey River, which flows through a region dissected by numerous tributaries including Elk Cr and Bear Cr. To the southeast, the headwaters of the N Fork Maquoketa River begin to emerge, shaping the local topography. This map illustrates the intersection of these waterways with a rigid section-line road grid, where long avenues such as 290th Ave and 300th Ave facilitate travel between scattered farmsteads. The placement of these settlements relative to Coffee Cr and Garretts Br reflects the historical reliance on local water sources for early agricultural development in this corner of the state.
