The Sacramento Bee reported that 18-year-old D'Artagnan Driscoll of Apache Junction, Arizona sent a rescue signal Sunday night after realizing he was running out of water. He started with over 50 pounds of supplies at the start of the trail.
"How I got lost was, I was hiking at night and I had a headlight on, and the trail was obscurred by snow, I got lost and set off my locator beacon at 11:57 at night," said D'Artagnan Driscoll.
Driscoll used a hand-held GPS device to call for rescue and was found about nine hours later when he realized he was in over his head.
"When I first saw the helicopter it was one of the happiest moments of my life," he said.
The teenager was on the Pacific Crest Trail in remote Alpine County on a two-month hike from Sonora to Canada. He says he used a cellphone application to find water sources on the trail but discovered that they had dried up.
Driscoll originally began his hike near the California-Mexico border but was driven to Sonora when he couldn't find water in Southern California.
