It is great also. Very rich colors, and it shows the depth by way of the darkness. I like the earlier one better though- in the prior shot, you have balanced lighting in the bottom where you have the dark spot this one. Also, as I look at it, the trees and your friend earlier shot point to the center of the photo, where you have the diagonal canyon going across to take you to the high plain- it is really a great composition- if I could go back, for a little better light, I would go there...
Congratulations on a great series, and if you have more of the Grand I would enjoy a link to the gallery. It is a destination that has eluded me, for some time. Know how that goes- plan on a trip, and every time something comes up...
See ya out there!
