About this map

The Boone River meanders through the eastern portion of this landscape, marking a distinct break in the geometric grid of the surrounding prairie. This area, where the borders of Webster, Wright, and Hamilton counties meet, is defined by an extensive drainage network including Ditch No 49 and Ditch No 86, which converted the natural wetlands into productive farmland. The Chicago and North Western railroad cuts a diagonal path across the northwestern corner, providing a vital link for the agricultural economy of Troy and Newark townships.

Local history is centered near the riverbanks at Troy Park and the nearby Troy Cem. The landscape reveals the industrial footprint of the era through scattered Gravel Pits, while Brewers Creek feeds into the main river valley from the south. The map provides a precise view of the rural infrastructure of the late 1970s, from section-line roads to the specific placement of farmsteads across Fremont and Colfax townships.
