Teen boy rescued after sliding down ledge at Mount Diablo State Park

SAN RAMON, Calif. -- A teenage boy was rescued after sliding partially down a ledge at Rock City in Mount Diablo State Park late Monday morning, a San Ramon Valley

Fire Protection District deputy chief said.

Fire crews responded at 11:16 a.m. to a report of a 14-year-old boy who was at Sentinel Rock with friends and climbed outside of a railing there, then slid down a ledge into an area where he couldn't climb back up, Deputy Chief Lon Phares said.

Phares said the boy "got lucky he didn't slide all the way" down the ledge, a distance of about 100 feet.

Crews set up a rope rescue operation, lowering a rescuer down to the boy and attaching a harness to him. The boy was then lowered the rest of the way down the ledge to safety, according to Phares.

He suffered only minor abrasions to a leg and did not require transport to a hospital, Phares said.
