1975 Map of Decorah 1 NW

USGS Topo · Published 1977

About this map

Highlandville and Locust anchor this mid-1970s orthophotoquad, which reveals the intricate agricultural patterns of Winneshiek County. Unlike traditional topographic maps, this aerial imagery captures the physical reality of the landscape as it was recorded on September 26, 1975. The fine-grained detail shows the winding stream valleys and the complex strip-cropping techniques employed by local farmers to manage the rolling Iowa terrain. The small community of Locust is visible at a crossroads in the southwestern portion of the sheet, while Highlandville occupies a more centralized position among the deeply carved drainages. This survey by the U.S. Geological Survey and the Iowa Geological Survey provides a direct visual record of farmstead placement and timbered ridges before modern land-use changes.
