Bear Valley, California

The same ground, surveyed 110 years apart. Drag the handle to wipe between them. Both sheets are United States Geological Survey originals; neither has been altered.

1891 2001

Bear Valley grew from 121 to 128 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

Matched by testing this settlement's coordinate against the published boundary of every sheet in the United States Geological Survey's historical collection. Each opens the scanned sheet at the Survey.

Regional context, not property-specific evidence. The federal wildfire occurrence database lists 168 fires within 5 miles of Bear Valley between 1992 and 2020, burning about 91 acres in total. 80 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:

• Lake Alpine
• Cape Horn

Every fire recorded in Alpine County

Regional context, not property-specific evidence. Museums hold 1,255 specimens collected within 10 miles of Bear Valley between 1874 and 1975: 1,145 Animalia, 87 Fungi, 23 Plantae. 12 distinct Species records are shown. Collected by A. C. Forrer, A. Forrer, A. W. Greeley 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 4 workings within 5 miles of Bear Valley: 2 occurrences, 2 past producers. 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

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.

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 1658018.
