The county history of 1911 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

The federal wildfire occurrence database lists 38 fires within 5 miles of Blacktop between 2011 and 2020, burning about 59 acres in total. None started naturally. 2 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:

• Byesville
• Ideal
• Kings Mine
• Kipling
• Lore City
• Buffalo

Museums hold 343 specimens collected within 10 miles of Blacktop between 1875 and 1975: 134 Fungi, 125 Animalia, 80 Plantae, 2 Unrecorded, 2 Protozoa. 12 distinct Species records are shown. Collected by Adams, W. (William), Adams, W. (William), Trautman, M. B. (Milton Bernard) et al., Adams, W.; Adams, S. 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.
