Your mission, if you choose to accept it, is to solve this canyon mystery, namely, what is this? Past stop 8, past the Cochise rock you'll see this set of pipes (?) and piles of rubble. (Click on the photo for a larger view.) Take the trail at the end of the road for a closer look. Of course, if you already know what this is, don't leave us in suspense! I'll post the true story as soon as I have it.
