About this map

Duncan serves as the primary settlement hub in this rural Hancock County landscape, where the agricultural grid is defined by a series of named avenues and streets. The geography is dominated by the headwaters of the Iowa River, with the West Branch Iowa River and East Branch Iowa River flanking the central farmlands. This 2010 survey illustrates the highly managed water systems of the region, specifically noted by the presence of Drainage Ditch Number 6, which channels water through the prairie toward the larger river branches.

Local heritage and community sites are well-preserved, including several burial grounds such as Saint John Cemetery, Saint Boniface Cemetery, and Liberty Cemetery. In the northern reaches of the quadrangle, Eagle Lake and the Garner Municipal Airport mark the transition from residential and agricultural use to specialized utility and natural water bodies. The layout provides a clear view of the road network, from Lake Ave to the eastern edge along Reed Ave, tracing the modern footprint of these historic Iowa crossroads.
