Bryce Gillies came to a clearing in the Grand Canyon and peered down at the Colorado River rushing past him. On either side of him were stark canyon walls enveloping him in this place of natural beauty. The 20-year-old was thirsty and hot after a long day of brutal hiking on this Saturday in mid-July, but he could do nothing about it. He had ditched his water bottles and food, and there was no way he could go back and reach them. He had jumped sheer rock faces - some more than 30 feet - on his way down, and it would be nearly impossible to climb back up them.
