WTF rock cairn

This is Mark's photo from Buckskin Gulch.
It's our little buddy next to a rock cairn. The rocks sit upon a large rock in the middle of the canyon and seem to signify only that this was some sort of flat place to build a rock cairn.
And then build another one next to it.
Apparently for the practice.

There are literally only two directions to go in a slot canyon: forwards and back. You can lost in terms of distance traveled (in which respect the cairns are unlikely to help you) but you cannot get lost in terms of direction without chemical assistance.

So we took a picture of Bongo next to the useless cairns, in order to chronicle their futility.
And because we were laid up a day due to an injured companion, and had nothing better t do with our time.
