8 of 36 shown

Selected from the Digital Public Library of America's 36 image records catalogued for this county. Every one shown here carries a public-domain status or a licence that permits reuse on a site that carries advertising; non-commercial, share-alike and restricted images are excluded. The selection is spread across the county's towns (at most eight per town), so no single institution's bulk upload crowds out the rest. Each opens the holding library's record, and the complete set at the Digital Public Library of America is one click away.

The county from the air

48 shown

Flown by the U.S. Geological Survey between 1937 and 1989, the Aerial Photo Single Frames collection is the definitive mid-century view of the land: fields, roads and rivers as the camera saw them. The Survey holds 9,623 frames inside the rectangle that bounds this county; the 48 frames below were taken over the county itself, chosen across the decades of flights (at most four a year from that rectangle), so one flight cannot crowd out the rest. The full set is free to browse and download at EarthExplorer under the dataset Aerial Photo Single Frames.
