CRESTLINE, Calif.—A wildfire in the San Bernardino National Forest about 55 miles east of Los Angeles tripled in size to approximately seven square miles on Sunday night. Smoke from the fire is casting a hazy pall in Las Vegas, more than 200 miles away.
The blaze in the San Bernardino Mountains east of Silverwood Lake and south of the high desert city of Hesperia burned from 1,500 acres on Sunday to 4,500 acres early Monday. Containment is estimated at just 5 percent.
Some 400 firefighters are working the blaze and more have been ordered.
