2022 Map of Sheridan

About this map

The settlement of Sheridan anchors the rolling landscape of northern Poweshiek County, where the township grid meets the Tama County line. This region is characterized by its agricultural geometry, defined by a dense network of numbered roads like 90th St and 320th Ave that navigate the headwaters of regional drainages. Local family histories are tied to the grounds at Sheridan Cem and Trinity Cem, which are situated among the gentle divides between Walnut Cr and Big Bear Cr. The terrain is a complex pattern of dendritic stream systems, including Elk Run and Stony Cr, which have dictated the placement of homesteads and farmsteads within the Public Land Survey System squares of Township 81 North. This detailed modern survey from the U.S. Geological Survey illustrates how the rural infrastructure remains fundamentally tied to the original 19th-century land divisions.
