These are the passages that mention it, exactly as the scans read.

Regional context, not property-specific evidence. The federal wildfire occurrence database lists 1 fire within 5 miles of London between 2020 and 2020, burning about 2 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:

• Amoy
• Carefree Estates
• Ganges
• Myers (historical)
• Rome
• Shelby

Every fire recorded in Richland County

Regional context, not property-specific evidence. Museums hold 82 specimens collected within 10 miles of London between 1839 and 1971: 34 Animalia, 27 Plantae, 21 Fungi. 12 distinct Species records are shown. Collected by Chase, H. (Hazel), E. Wilkinson, Eric G. Chapman 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.
