It was probably an established wilderness camping spot. To camp down in the Grand Canyon, wilderness permits are required so they can control the amount of people down there as it's a very special ecosystem. Also, there are strict regulations about where you can camp, esp. when you have a group of people. (I've camped down there twice at Bright Angel Campground-really a neat experience.)

Leave it to the government....
I guess I won’t be experiencing camping in that canyon. Momma didn’t raise no idiot.
