The federal wildfire occurrence database lists 21 fires within 5 miles of Rocky Hill between 2007 and 2019, burning about 45 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:

• Winchester
• Ridgeland
• Clay
• Limestone (historical)
• Pattonsville
• Pyro

Every fire recorded in Jackson County

Museums hold 671 specimens collected within 10 miles of Rocky Hill between 1899 and 1974: 302 Animalia, 217 Plantae, 147 Fungi, 3 Protozoa, 2 Unrecorded. 12 distinct Species records are shown. Collected by A. Cronquist, A. M. Evans, Bartley, F. 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 federal mineral resources record lists 4 workings within 5 miles of Rocky Hill: 2 past producers, 1 producer, 1 occurrence. 1 still produces. What was taken out: Limestone, General, Stone, Crushed/Broken, Fire Clay (Refractory), Aluminum, Titanium, Silica, Iron. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.
