The mandatory evacuation zone for the Caldor Fire has been extended east to Echo Summit, and warnings were imposed for the first time in Alpine County.

The fire was estimated at 136,643 acres (213 square miles) on Thursday morning, and containment was at 12%. The spot fire north of Kyburz joined with the main fire, and flames burned close to Highway 50 for a 5-mile stretch east of that.

Since Aug. 20, Highway 50 has been closed between Pollock Pines and Meyers.

All the evacuation orders so far are in El Dorado County, except for a very small area of Placer County near Loon Lake. Warnings have also been issued in Amador County.

All of Eldorado National Forest has been closed to the public through Sept. 30.
