History of Columbiana County, Ohio, published 1879 names this settlement in its chapter on Middleton Township. These are the passages that mention it, exactly as the scans read.

Regional context, not property-specific evidence. The federal wildfire occurrence database lists 36 fires within 5 miles of Clarkson between 2005 and 2020, burning about 24 acres in total. None started naturally. None was recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.

Settlements close enough to share some of these fires:

• Rogers
• Achor
• East Carmel
• Middle Beaver (historical)
• Mill Rock
• Negley

Every fire recorded in Columbiana County

Regional context, not property-specific evidence. Museums hold 686 specimens collected within 10 miles of Clarkson between 1885 and 1975: 432 Animalia, 226 Plantae, 27 Fungi, 1 Unrecorded. 12 distinct Species records are shown. Collected by Adler, K. K., Andreas, B.; Cusick, A.W., Armbruster, D. C. (Daniel C.) and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

Regional context, not property-specific evidence. The federal mineral resources record lists 3 workings within 5 miles of Clarkson: 3 past producers. None of them still produces. What was taken out: Sand and Gravel, Construction, Clay, Bituminous. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.

Every working recorded in Columbiana County
