Family members apparently did not immediately realize their father was missing, and then contacted a missing persons detective in Los Angeles who helped them figure out that he had been gone for some time.
The detective narrowed the search area using cell phone towers, text messages and debit card purchases, Chardonnay Lavau told NBC and other organizations.
Lisa Lavau told KCAL-TV her family had not heard from her father for several days.
After narrowing the search area, "We stopped at every ravine, and looked over every hill and then my brother got out of the car and we kept screaming and the next thing we heard Dad saying 'help, help,' and there he was," Lisa Lavau said.

So, what would YOU have done in this man's situation?
Create a smoke fire during the day? Use a mirror? A whistle or even an air horn probably wouldn't be heard by the passing cars. Hmmm, better recheck my car kit.
