The county history of 1901 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 33 fires within 5 miles of Swartz Mill between 2003 and 2020, burning about 157 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:

• Geneva
• Horns Mill
• Blue Valley Acres
• Pleasant Hill
• Bremen
• North Berne

Museums hold 1,460 specimens collected within 10 miles of Swartz Mill between 1839 and 1975: 877 Animalia, 339 Fungi, 230 Plantae, 7 Protozoa, 5 Unrecorded, 2 Chromista. 12 distinct Species records are shown. Collected by A. Schrader, Angerman, C. (Carl) & Triplehorn, C. A. (Charles A.), Asa Gray; W. S. Sullivant 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 2 workings within 5 miles of Swartz Mill: 2 past producers. None of them still produces. What was taken out: Sand and Gravel, Construction. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.

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 1063046.
