1975 Map of Augusta NW

About this map

Augusta and La Prairie anchor this mid-1970s orthophotograph, providing a detailed photographic record of the agricultural landscape in Schuyler County. The map is built from high-altitude aerial imagery taken on May 1, 1975, revealing the precise layout of farmsteads, woodlots, and drainage patterns across the Illinois prairie. This specialized series, produced by the U.S. Geological Survey and the State Geological Survey, uses photoimagery instead of traditional topographic line work to show the actual footprint of the land as it appeared during the spring planting season. Genealogists and local historians can use this visual data to identify the exact location of historical rural structures and field boundaries that are often simplified on standard contour maps.
