The county history of 1862 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

The federal wildfire occurrence database lists 33 fires within 5 miles of Pleasant Valley (historical) between 2004 and 2020, burning about 26 acres in total. None started naturally. 5 were 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:

• Amity
• Apple Valley
• Buckeye City
• Danville
• Four Corners
• Howard

Every fire recorded in Knox County

Museums hold 403 specimens collected within 10 miles of Pleasant Valley (historical) between 1837 and 1974: 345 Animalia, 35 Fungi, 22 Plantae, 1 Protozoa. 12 distinct Species records are shown. Collected by A. P. Morgan, Andriessen, H., C F WALKER 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.
