TWO SPELUNKERS RESCUED FROM THUNDER CANYON CAVE
May 3, 2010 (Boulevard) – Rescue crews worked through the night to free two men trapped in Thunder Canyon Cave northeast of McCain Valley Road in Boulevard. Brett Colvin of Escondido and Jim Ness of San Diego were airlifted from the scene and treated by Campo Reservation paramedics for hypothermia.
San Diego Sheriff’s Department received a call last night at 6:30 p.m. after Colvin became trapped in a narrow passageway about 200 feet from the cave entrance. Due to the location, extremely rugged terrain, and specialized nature of the rescue, several allied agencies responded to assist in freeing the trapped men. They included U.S. Border Patrol’s Borstar Unit, San Bernardino Sheriff's Cave Rescue Team, San Diego Sheriff's Search and Rescue, Mountain Rescue Team, Bureau of Land Management Park Rangers, Sheriff's Wireless Unit, Sheriff's Astrea helicopters and San Diego Fire's Copter 1.
Colvin was subsequently freed early Monday morning, at about 3:45 a.m. Ness also required rescue assistance to exit the cave.
