Regional context, not property-specific
evidence. Museums hold 1,756 specimens
collected within 10 miles of Keeler, Diadatus, House between 1850 and
1975: 1,686 Animalia, 41 Fungi, 27 Plantae, 1 Unrecorded, 1 Chromista. 12 distinct Species records are shown.
Collected by A C Whitney, A S BRADSHAW, A. P. Morgan 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
2 workings within 5 miles of Keeler, Diadatus, House: 1 past producer, 1 producer.
1 still produces. What was taken out: Clay. Distance is straight-line from the
map coordinates, so a quarry counted here may appear on a neighbouring
settlement's page as well.
Regional context, not property-specific
evidence. The National Weather Service names
Galena, the town this property stands in, in 14 storm reports between 1994 and 2020: 7 thunderstorm wind, 5 hail, 1 tornado, 1 flood.
No death or injury is recorded in these reports. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
The tornado touched down and moved briefly along Big Walnut Road near the Hoover Reservoir. Trees were damaged along the path due to the tornado. In addition, a few shingles were torn off of a house. Based on the damage, wind speeds were estimated around 75 miles per hour.

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.
