The federal wildfire occurrence database lists 8 fires within 5 miles of Harper between 2007 and 2020, burning about 32 acres in total. None started naturally. 1 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:

• Lyndon
• Roxabell
• South Salem
• Fruitdale
• Lattaville
• Musselman

Every fire recorded in Ross County

Museums hold 528 specimens collected within 10 miles of Harper between 1898 and 1975: 499 Animalia, 23 Plantae, 6 Fungi. 12 distinct Species records are shown. Collected by Alexander, R.D., Barnes, M. (Mark) & Cloggett, L., Bowen, C. A. (Charles A.) 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.

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 1064797. The sheet list is computed by point-in-boundary test against the United States Geological Survey's historical topographic inventory.
