An account from the chapter on Jackson township, in the words of 1900.

The federal wildfire occurrence database lists 36 fires within 5 miles of Leo between 2006 and 2020, burning about 232 acres in total. None started naturally. 2 were 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:

• Pine Grove
• Buffalo
• Savageville
• Big Rock
• Eastburn (historical)
• Oakland

Every fire recorded in Jackson County

Museums hold 1,318 specimens collected within 10 miles of Leo between 1878 and 1975: 661 Animalia, 594 Plantae, 58 Fungi, 3 Unrecorded, 2 Protozoa. 12 distinct Species records are shown. Collected by 'Odell, D., A. Cronquist, A. M. Evans 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.

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 1070814.
