collected within 10 miles of Williamson Mound State Memorial between 1870 and
1975: 633 Animalia, 142 Plantae, 116 Fungi, 1 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.
Regional context, not property-specific
evidence. The federal mineral resources record lists
5 workings within 5 miles of Williamson Mound State Memorial: 3 past producers, 1 plant, 1 producer.
2 still produce. What was taken out: Sand and Gravel, Construction, Limestone, General, Stone, Crushed/Broken. Distance is straight-line from the
map coordinates, so a quarry counted here may appear on a neighbouring
settlement's page as well.

When this property was proposed for the
National Register, someone wrote the case for it: what the building is,
and why it matters. That document is a federal record in the public domain.
It is quoted below word for word, never summarised. The text was read off the scanned case file by machine, so the
occasional stray character is the recogniser's and the 1970s
typewriter's.
