DAVIS  (AP) — A Northern California man who was lost in the wilderness for more than a week survived on runoff and pine nuts, his father said.

Daniel Thompson, 25, of Davis turned up around a campground in Lake County on Sunday, the Davis Enterprise reported on Tuesday.

His father, Brian Thompson, told the newspaper he had been missing since April 13 after leaving on a camping trip.

He lost control of his car and went off a road in a rural area northwest of Clear Lake. With no cellphone reception, he wandered the wilderness searching for help, surviving on pine nuts and runoff, the elder Thompson said.

Daniel Thompson declined an interview request from the Davis Enterprise.

But his father said he grew up learning about edible plants, and pine nuts were among his favorite.

"He may never want to eat them again," Brian Thompson said.

Friends and family became concerned after the younger Thompson failed to show up for a dinner meeting with a friend and later his job at the University of California, Davis.

Luke Macaulay, a Berkeley resident, told the Davis Enterprise that he discovered Daniel Thompson's abandoned car down a steep embankment on Saturday evening. The passenger door was open and the key was in the ignition.

He found the driver's license. He and his girlfriend called police after looking up Daniel Thompson's name on her cellphone and discovering he had been reported missing.
