If it's not JAG, then my guess is that it was either a member of the tribe, a migrant worker (they are all over the place up there and many illegals live in that canyon and cross over from the surrounding areas) or a hunter. BTW, the google map of the area doesn't do justice to the Pala Indian Reservation--it is much larger than the area showing on the map. When we were driving around the area 2 weeks ago, there was one point where Lake Henshaw was on the right, right next to us, and part of the Indian reservation was on the left. Can't really tell that from the map.
