The county history of 1881 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

Museums hold 695 specimens collected within 10 miles of Plateau Acres between 1840 and 1974: 444 Animalia, 210 Plantae, 40 Fungi, 1 Chromista. 12 distinct Species records are shown. Collected by 73.7; J.H., A. Barron, A. N. Leeds 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.
