1956 Map of Treynor

About this map

Treynor stands as the primary settlement on this mid-century survey of southwest Iowa, situated where the high ground transitions into the drainage basins of the Missouri River system. The landscape is defined by the winding paths of Middle Silver Creek and Silver Creek, which cut through the townships of Hardin, Washington, and Silver Creek. This 1950s mapping project, conducted as part of the Missouri River Basin development program, captures the rural infrastructure of Pottawattamie and Mills counties just as aerial photogrammetry was becoming the standard for topographic precision. Notable landmarks for local historians include the Boxelder Sch near the southern boundary and several rural crossings, including a Footbridge over the creek branches. The map provides a clear record of the section-line road network and bridge locations like BR 1092 that served the agricultural community during this period.
