This was taken at one of the shallower and wider sections of the longest and deepest slot canyon in the world, somewhere near the Utah/Arizona border. It is surprisingly (and relatively speaking) non-technical, considering its length. Haven't had an opportunity to do the whole thing yet. Maybe when the monsoons are over.
Sigma DC 10-20 @ 12mm

I stumbled across your gallery several times, always stopping in awe and finally I got over my laziness to express my gratitude for sharing those pictures with us. I really think, I would have loved to see all those places you visited but I am glad that I could see them through your pictures.
