The federal wildfire occurrence database lists 40 fires within 5 miles of Oak Hill between 2004 and 2020, burning about 20 acres in total. None started naturally. 3 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:

• Hollisters (historical)
• Zuck
• Brinkhaven
• Umbria (historical)
• Howard
• Millwood

Museums hold 252 specimens collected within 10 miles of Oak Hill between 1890 and 1974: 220 Animalia, 19 Plantae, 13 Fungi. 12 distinct Species records are shown. Collected by C F WALKER, C. Stein, R. Johnson & J. Jenkinson, Collector unknown 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.

Every working recorded in Knox County

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 1062921.
