SAN DIEGO — A man was pulled from his SUV and rushed to the hospital by helicopter after he crashed down an embankment near Poway Thursday.

Emergency crews were called to the crash off State Route 67 around 11 a.m. SkyFOX flew over the wreckage of an SUV at the bottom of a ravine near Rockhouse Road, not far from Potato Chip Rock.

A man in his 60s had to be rescued from the 2011 Land Rover and transferred to an air ambulance, according to California Highway Patrol. He was unconscious when paramedics reached him, but officials weren’t sure what caused the man to drift off the road in the first place.

CHP said alcohol and drugs were not suspected as a factor in the crash, adding that the man may have had a medical emergency before he veered off the highway. He is expected to survive.

Around noon, a team in orange jumpsuits spread out in a line and started methodically searching the hillside down to where the vehicle came to rest. It wasn’t immediately clear what they were searching for.
