RAMONA, Calif. -- Authorities Thursday released the name of a 16-year-old boy who died at a waterfall near Ramona that has become a popular summer party spot for young people.

Joseph Meram of El Cajon plunged about 80 feet from the granite rocks at Cedar Creek Falls, hitting his head on boulders on the way down. Witnesses said Meram was climbing on the steep rock face to the right of the falls when he slipped and tumbled down the rock face and into the natural pool at the bottom.

Friends of the critically injured El Cajon teen made a 911 call and carried him up a steep slope to a clearing, where an emergency-services helicopter crew picked him up, Cal Fire Capt. Mike Mohler said. The boy was flown to a Ramona-area fire station, where he was pronounced dead. His name was withheld pending family notification.

Meram was a student at Valhalla High School in El Cajon. Thursday, friends filled his Facebook page with tributes, memories and condolences.  

The U.S. Forest Service has closed the trail to Cedar Falls from San Diego Country Estates while the accident is investigated.
