Museums hold 894 specimens collected within 10 miles of Park Hills Crossing between 1839 and 1975: 661 Animalia, 125 Plantae, 102 Fungi, 5 Protozoa, 1 Unrecorded. 12 distinct Species records are shown. Collected by ?, A JOHN, A. H. Bauer 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.

Every working recorded in Greene County

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 2517244.
