According to a Los Angeles Times Article: The fire began around 4:00 p.m. Wednesday near Jenks Lake Road, charring 50 acres near a cluster of summer camps operated by churches and the YMCA, according to the U.S. Forest Service. But the blaze, which is 5% contained, grew overnight, moving east as it consumed timber and threatening several structures. The San Bernardino National Forest received rain last Friday, but it was not enough to relieve dry conditions. The Lake fire quickly grew in the afternoon from 1,500 acres to 7,500 acres because of dry, windy conditions, said Anna Bribiescas, a spokeswoman for the U.S. Forest Service. By 7 p.m., the fire had spread to 10,000 acres, making it the largest blaze this year on the state’s national forests. Fire officials have also ordered evacuations for areas east of Angelus Oaks, Onyx Summit, Barton Flats, Seven Oaks and homes off of Rainbow Lane. Hiking trails into the San Gorgonio Wilderness area were closed because of the fire. The Pacific Crest Trail is also closed from Whitewater Preserve to Onyx Summit. Jenks Lake Road has been shut down, and Highway 38 is closed between Angelus Oaks to Lake Williams.
