Investigators have determined that the 2,190 acre Etiwanda Fire was started by an escaped illegal campfire. Once conditions in Day Canyon were deemed safe, investigators hiked into the remote upper portion of the canyon, and located evidence of an illegal campfire. Investigators believe the illegal campfire may have been smoldering for a few days until the strong winds blew embers into nearby brush. Wood and charcoal fires are only permitted in designated campgrounds and picnic areas and never in the general forest area.
