PLYMOUTH, Calif. (AP) — A fast-moving wildfire in Northern California has burned at least two structures and prompted the evacuation of homes along a rural road east of Sacramento.

CalFire says an unknown number of homes on Sand Ridge Road off Highway 49 were evacuated.

A CalFire spokeswoman says the fire broke out Friday afternoon in a riverbed along the Amador and El Dorado county line, north of the town of Plymouth. She says the fire crossed the river into more rugged terrain, spreading to about 1300 acres of brush and woodland.

The fire sent a huge plume of smoke across the region.

Investigators were trying to determine whether a burned car found by the riverbed ignited the fire.
