Regional context, not property-specific evidence. The federal wildfire occurrence database lists 131 fires within 5 miles of Swanson Corners between 2004 and 2020, burning about 489 acres in total. 13 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.

Collected by A. Albee, A. B. Seymour, A. C. Gibson 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.
