The county history of 1900 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 34 fires within 5 miles of Harshasville between 2004 and 2020, burning about 72 acres in total. None started naturally. 4 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:

• Unity
• Wheat Ridge
• Youngsville
• Irvington (historical)
• Dunkinsville
• Mount Zion (historical)

Every fire recorded in Adams County

Museums hold 724 specimens collected within 10 miles of Harshasville between 1866 and 1975: 391 Animalia, 238 Fungi, 77 Plantae, 18 Protozoa. 12 distinct Species records are shown. Collected by A. B. Seymour, A. Cronquist, A. J. Sharp 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 1064803. The sheet list is computed by point-in-boundary test against the United States Geological Survey's historical topographic inventory.
