Few days ago while browsing around Arizona in Panoramio I found Horseshoe Bend, one of those places where satellite and surface photos combine so good that you almost get the feeling being physically there, as you can see in the mini-panoramio below:
Horseshoe Bend is a meander of the Colorado River located near the town of Page, Arizona, in the United States. I didn't found very much information about this place in the Wikipedia article, but I found some great shots (1, 2 and 3).
In the same area it is located the Antelope Canyon, where some breathtaking photos (1, 2 and 3) have been mapped. Definitively Arizona is full of interesting places.
