Flown by the U.S. Geological Survey between 1937 and 1989, the Aerial Photo Single Frames collection is the definitive mid-century view of the land: fields, roads and rivers as the camera saw them. The Survey holds 13,050 frames inside the rectangle that bounds this county; the 48 frames below were taken over the county itself, chosen across the decades of flights (at most four a year from that rectangle), so one flight cannot crowd out the rest. The full set is free to browse and download at EarthExplorer under the dataset Aerial Photo Single Frames.

August 2020Tornado (EF1)Coyoteville-A mesoanticyclone embedded within a deep pyrocumulonimbus updraft inside the Loyalton wildfire perimeter generated an EF1 rated anticyclonic tornado that snapped several quaking aspen trees (DI 27, DOD 4) along a 0.09-mile path on the northeast facing slope of Roberts Canyon. The tornado spun up 0.37 miles south-southwest of the intersection of Forest Service Road 182 and Forest Service Road 31182 and dissipated 0.46 miles south-southwest of the aforementioned intersection.

August 2020Tornado (EFU)Plumas-Bystanders along CA 70 and US 395 near Hallelujah Junction captured multiple videos and photographs of an anticyclonically rotating tornado pendant to the base of a pyrocumulonimbus cloud. The tornado caused no damage from which the NWS could assign an EF-scale rating as it traversed across an area of burned sagebrush. From photographs and video evidence, the approximate path of the tornado was calculated. The tornado traveled along a 3.16-mile path from the head of Roberts Canyon to 1.33 miles southwest of Hallelujah Junction. The maximum path width was approximately 156 yards. No injuries or deaths occurred with this tornado.
