About this map

Plessis serves as a central point of reference in this O'Brien County landscape, situated on the prominent glacial upland known as the Coteau des Prairies. This physiographic region shapes the hydrology of the area, with numerous watercourses like Waterman Cr and Plessis Cr draining the agricultural fields. The terrain is defined by a dense grid of section roads, including Sorrel Ave and Tanager Ave, which speak to the enduring township and range system of Northwest Iowa.

Genealogists will note the Randolph Cem located in the southeastern portion of the map near Little Waterman Cr. The map captures the quiet intersection of drainage and infrastructure, where the Floyd River and Epping Cr carve subtle valleys through the high prairie. The prominence of family-named or locally significant roads like Taft Ave and Tyler Ave underscores the local-history value of this 2018 survey.
