The federal wildfire occurrence database lists 31 fires within 5 miles of Keystone between 2006 and 2019, burning about 64 acres in total. None started naturally. 7 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:

• Four Mile
• Camba
• Banner
• Grahamsville
• Jackson Heights
• Clay

Museums hold 830 specimens collected within 10 miles of Keystone between 1899 and 1974: 377 Animalia, 287 Plantae, 160 Fungi, 3 Protozoa, 3 Unrecorded. 12 distinct Species records are shown. Collected by A. Cronquist, A. M. Evans, A.J. Sharp 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.
