The federal wildfire occurrence database lists 16 fires within 5 miles of Blue Rock between 2002 and 2019, burning about 27 acres in total. None 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.

Settlements close enough to share some of these fires:

• Merriam
• Gaysport
• Stone
• Cedar Run
• Confederate Crossroads (historical)
• Museville

Every fire recorded in Muskingum County

Museums hold 246 specimens collected within 10 miles of Blue Rock between 1893 and 1971: 229 Animalia, 12 Plantae, 5 Protozoa. 12 distinct Species records are shown. Collected by Adams, W.; Starrett, J., Adams, William, Adler, K. K. 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.

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 1048400.
