Regional context, not property-specific evidence. The federal wildfire occurrence database lists 157 fires within 5 miles of Lake Alpine between 1992 and 2020, burning about 4,142 acres in total. 81 started naturally. 1 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:

• Bear Valley
• Cape Horn

Every fire recorded in Alpine County

Regional context, not property-specific evidence. Museums hold 1,293 specimens collected within 10 miles of Lake Alpine between 1874 and 1975: 1,173 Animalia, 93 Fungi, 27 Plantae. 12 distinct Species records are shown. Collected by A. C. Forrer, A. Forrer, A. W. C. T. Herre 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 Lake Alpine: 2 occurrences, 2 past producers, 1 prospect. None of them still produces. What was taken out: Gold, Silver, Clay, Molybdenum. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.

Every working recorded in Alpine County

Regional context, not property-specific evidence. The National Weather Service names Lake Alpine in 4 storm reports between 1998 and 2020: 4 hail. 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.

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 1658929. The sheet list is computed by point-in-boundary test against the United States Geological Survey's historical topographic inventory.
