Zebra Slot Canyon

This a Winter shot? I've seen this in bright sun, looks very nice with more subdued lighting too. Very nice colors in this.

The mixture of the cold tones of the reflected sky with the warm tones of the stone (and sun?) in the back is very nice...
Personally, I might have cropped it to square, removing some of the left side. I think it would enhance the tunnel effect a bit... but this is just a vague feeling of me...
