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 17 fires within 5 miles of Pleasant Hill between 2003 and 2020, burning about 80 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:

• Bremen
• Horns Mill
• North Berne
• Blue Valley Acres
• Geneva
• Swartz Mill

Museums hold 2,492 specimens collected within 10 miles of Pleasant Hill between 1839 and 1975: 1,827 Animalia, 395 Fungi, 256 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.
