The fire began on July 17, 2015. The areas most impacted were adjacent to Interstate 15, where the Cajon Pass passes through the San Bernardino National Forest. The fire spread to 4,250 acres, and burned homes and other buildings, as well as numerous vehicles stranded on the interstate. Seventy-four passenger vehicles and trucks were burned along the highway or in neighboring communities due to the fire. The fire closed Interstate 15, the main highway connecting Southern California with Las Vegas, Nevada, during the first day of the blaze.One-thousand fire fighters battled the blaze during the height of the fire, which as of the evening of July 17 was five percent contained. Mandatory evacuations were ordered for the towns of Phelan and Baldy Mesa, which were threatened or impacted by the fire. Two-hundred-four people utilized an emergency shelter set up at Serrano High School, in Phelan. The evacuation orders were lifted as crews worked to contain the fire. On the evening of July 18, the fire was reported to be 45% contained, after a rain storm from the remnant moisture of Hurricane Dolores brought cooler temperatures to the chaparral fueled fire. By the following morning, the fire was reported to be 60% contained. On Monday, July 20, the fire was reported to be 75% contained, but had also grown from 3,500 to 4,250 acres. The fire was fully contained on July 21, and fire fighters remained on scene to douse hot spots in the burn area. The remnants of Hurricane Dolores assisted with putting the fire out by drenching the area the same weekend, while causing other damage in Southern California.The presence of unmanned aerial vehicles (UAVs/drones) in the area that interfered with fire fighting efforts has renewed discussion of legislation to limit the operation of drones in the United States. In response to the drone activity over active wildfires, San Bernardino County, the California State Legislature and the Congress of the United States have all proposed restrictions on privately owned drones.
