SWALL MEADOWS, Calif. — An out-of-control wildfire at the foot of the Sierra Nevada grew to 500 acres after prompting the mandatory evacuation of two small California towns near the Nevada state line.

Cal Fire officials said Saturday that one residence and one outbuilding have burned in the vegetation fire on the border of Inyo and Mono counties.

Capt. Liz Brown says a few dozen people were evacuated Friday from Paradise and Swall Meadows, two communities northwest of Bishop. No injuries are reported.

The Inyo County Sheriff Department says the blaze is burning west of Highway 395 at the Sherwin Grade.

Firefighters with several agencies have responded, including the Orange County Fire Authority in Southern California.

The cause of the fire is under investigation.
