On Tuesday when I arrived in the office in California, I heard the story and volunteered to assist in a rescue mission.
Early Wednesday we headed up to Castle Rock. Accompanying us was one of Joels friends, Tim.
Once Joel got to the base of the rock he quickly located his cell phone. Luckily it still worked. He also found three other phones, and some Oakley sunglasses. Neither of the phones seemed to be working.
When we got back to the office we gave the phones a charge, and two of the phones, a Samsung Galaxy SII, and an Apple iPhone 4, actually worked. Joel has tried to contact the owners to return them. (as of this writing one of the owners has responded but the phone has not yet been returned - hopefully soon).
This was a unique adventure, but a fun one. I'll leave you with some more pictures from Castle Rock State Park.
