Christopher Sylvia began his hike on the evening of February 12 from the intersection of the Pacific Crest Trail and Highway 74 east of Anza. He has not heard from since February 16, when he telephoned a friend and said he wanted to be picked up. The friend was supposed to meet Sylvia on February 17 at the Lieu Quan Meditation Center at 31130 Chihuahua Valley Road near Warner Springs. Search teams found Sylvia's camping gear abandoned near the rendezvous point on Chihuahua Valley Road.
