1975 Map of Decorah 3 NE

USGS Topo · Published 1977

About this map

Calmar and Ossian anchor this 1975 orthophotoquad in Winneshiek County, Iowa, providing a literal view of the landscape during the mid-seventies. This imagery, captured by the Geological Survey in late September, reveals the intricate patchwork of contour-plowed fields and windbreaks characteristic of the region's agricultural heritage. The diagonal path of the railroad and the primary highways connecting these two settlements are clearly visible, cutting across the rhythmic patterns of the farmland. Unlike a traditional topographic map, this aerial survey allows researchers to see the exact footprint of farmsteads and the density of local woodlands at a specific moment in time before further modern development altered the rural layout.
