2010 Map of Peosta

About this map

Peosta serves as a central hub in this section of Dubuque County, where a grid of rural roads connects several established settlements and local historical sites. The landscape is defined by the drainage patterns of Whitewater Creek and the multiple branches of Middle Fork Catfish Creek, which dictate the placement of early homesteads and transport corridors. Genealogists will find a high concentration of burial sites, including the New Melleray Abbey Cemetery near the southern boundary and the Saint John the Baptist Catholic Cemetery in Centralia. The geography reflects a transition from agricultural land to regional infrastructure, seen in the proximity of the Dubuque County Fairgrounds to the small community of Julien. Cultural markers like the Peosta Post Office and the Michael Schmitt Cemetery offer specific points of reference for those tracing family lineage or early 21st-century development in the Iowa interior.
