Every property in this county listed on the National Register of Historic Places, with the year it was listed and the federal nomination document.
Drawn when these were printed as single large sheets: the town seen from the air, and the county divided into its farms with every owner named. Each opens the original at the Library of Congress.



Selected from the Digital Public Library of America's 4 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.
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 1,555 frames inside the rectangle that bounds this county; the 45 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.













































The thermometers that kept this county's weather, and the gages that measured the flow of its streams, as the federal records hold them. The extremes below are measured values from those records, not estimates.
Who lived here in 1950, one enumeration district at a time, as the Census Bureau described each district. Each row opens its official National Archives result, with Population Schedules and ED Maps available there.

| September 1993 | Tornado (F2) | Angelica | $500,000 | The tornado first touched down and uprooted or snapped a number of large trees. A large annex to a barn disintegrated as the tornado passed by. The debris was scattered downwind across a field. A pickup truck was moved about 75 feet down a road and tossed into a pole. The tornado then crossed a field and uprooted a few large trees that all fell in roughly the same direction. A nearby house sustained significant structural damage and the entire structure was shifted slightly off its foundation. The tornado crossed a field and a stand of large trees. Many of the trees were knocked down in a very "chopped up" pattern. |

Museum specimens collected in and around this county - inside the rectangle that bounds it - and catalogued with a date and a place: 1,170 of them, by kingdom 930 animalia, 192 plantae, 37 fungi, 4 chromista, 4 unrecorded. Each is a physical object in a named collection, not a sighting. Held by CUMV, MSU, Ohio State University Acarology Laboratory, Columbus, OH (OSAL), SDC, University of Alberta Museums (UAM), CM among others, and each settlement page carries the specimens collected near it.
The oldest of them. A specimen proves something was collected on that day; its absence proves nothing.
