It's been some years since I visited this spot (thought it was called Natural Arch) but it sticks in my mind as one of the best locations I've ever been to. You've done a wonderful job with the HDR to bring out the colours and tonal range.
I sure wish they would allow different size limits for panoramics... I would love to see a larger version, but that won't affect my vote. Wonderful lighting and a fantastic pano... 8
