The federal wildfire occurrence database lists 54 fires within 5 miles of Denver between 2006 and 2020, burning about 196 acres in total. None started naturally. None was 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:

• Harris
• Pleasant Grove
• Summithill
• Yankeetown
• Alma
• Brownsville

Museums hold 935 specimens collected within 10 miles of Denver between 1874 and 1975: 745 Animalia, 123 Fungi, 59 Plantae, 6 Protozoa, 2 Unrecorded. 12 distinct Species records are shown. Collected by A. C. Lincoln, Allen, J. (John), Atkinson, George 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.

The National Weather Service names Denver in 1 storm report between 2024 and 2024: 1 thunderstorm wind. 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.
