A number of Sonoma County firefighters are working with thousands of firefighters on the massive Yosemite area blaze, local fire officials said Monday.

Glen Ellen, Sonoma Valley and Windsor firefighters have gone to the raging fire. They left late Friday night and Saturday.

They join a team of four from Santa Rosa Fire, which has been there with a wildland engine since the middle of last week.

As of Monday morning the Yosemite fire had consumed about 150,000 acres or 225 square miles, leading to mandatory evacuations of multiple areas.

Federal fire officials Monday morning had estimated the fire was 15 percent contained and reported 23 structures had burned, with about 4,500 structures threatened and two people injured.

The fire now is considered one of the largest in state history.

Almost 3,500 firefighters were on the lines of the Tuolumne County fire.

Glen Ellen and Windsor fire sent tactical water tenders — two of 36 water tenders on the effort. And Santa Rosa and Sonoma Valley firefighters drove down in department wildland engines — among 87 fire engines.

Also, Santa Rosa fire Capt. Keith Flood went to Yosemite to help manage the huge firefighting effort.

Other major fires continue to burn around the state, including the Corral Complex blaze in Humboldt County's Trinity Alps. That fire started Aug. 10, from a lightning strike.

As of Monday it had burned about 11,700 acres and remained out of control, with just 5 percent containment.

Fire officials reported 125 structures threatened and 1,062 firefighters on duty.

Forestville and Sonoma Valley fire departments have sent at least three firefighters each with water tenders.

Ranking Santa Rosa firefighters also went for several days to help manage the Corral Complex fire.
