I spent a few days in Sedona and took a day trip to the Grand Canyon (Sedona and Grand Canyon photo album). I was very lucky in that one night the weather cleared completely and I was able to experiment with long exposure imagery using only the light of the full moon.
I also experimented with HDR a little more.
The daytrip to the Grand Canyon was also great; the day was cold but clear and beautiful.
Here is a 6 image panorama of the Grand Canyon South Rim from Yavapai Point.
