Christopher Stevens Sylvia, 28, disappeared from the Pacific Crest Trail in San Diego County after starting a southbound hike from the Anza area on February 12, 2015. On February 16 he phoned a friend and said to be picked up the next day at a Buddhist temple on Chihuahua Valley Road near Warner Springs, but he never arrived at the rendezvous.

On February 20 another hiker found Sylvia’s gear — backpack, sleeping bag, and identification — abandoned near mile marker 127 of the PCT, close to Mike’s Place. Extensive search and rescue efforts followed but produced no further clues. Family members described him as an experienced outdoorsman and said it was uncharacteristic for him to hike alone or to leave his gear behind.

The case remains unsolved. If anyone hiked that section of the PCT in mid February 2015 or has information about sightings near mile marker 127 or Chihuahua Valley Road, please share what was seen or heard.
