The county history of 1858 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 1 fire within 5 miles of Washington Knoll between 2010 and 2010, burning about 1 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:

• Beckley Addition
• Bixford Green
• Blacklick Estates
• Brice Meadows
• Bright (historical)

Every fire recorded in Franklin County

Museums hold 697 specimens collected within 10 miles of Washington Knoll between 1895 and 1975: 686 Animalia, 6 Fungi, 3 Unrecorded, 1 Plantae, 1 Chromista. 12 distinct Species records are shown. Collected by C. A. Petrovic, C. H. R., Caldwell 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.
