A 21-year-old Rocklin man fell 30 or 40 feet from a cliff Thursday at the north end of Portuguese Beach on the Sonoma Coast and was airlifted to Santa Rosa Memorial Hospital for treatment of his injuries, authorities said.

The patient was alive and talking when emergency personnel arrived and may have escaped major injuries, they said.

The man, whose name was not available, was staying with his family at a nearby rental house when he and his brothers were on the beach and he decided to climb the cliff, fire and state parks personnel said.

He got about halfway up before tumbling down the rocky face to the beach below around

12:30 p.m., state park Ranger Greg Probst said.

The man had at least a nosebleed, torso abrasions and leg injuries, Probst said, but he was airlifted because of the possibility of spinal injuries.

The Sonoma County sheriff's helicopter landed on the beach and transported him to Memorial Hospital, sheriff's Sgt. Ed Hoener said.

His condition was not immediately known.
