Looks like something cooking just south of Lake Davis, above Portola.
PNF Wildcad has it as Grizzly fire.
Someone kicked the aircraft hornets nest and T160 and T131 launched from RDD and MCC, as well as Grass Valley’s S2’s and C514.
Edit: Lat/Lon on wildcad seems off. Road description is more accurate, roughly Grizzly Rd and Old Grizzly Rd, south of there and north of Cedar Ravine Rd. Google Map estimate
T89 to Chester, T88 to Reno/Stead
