Havasu Falls Panorama, Havasupai, Arizona:
What could easily be a scene from some tropical, exotic location is actually an image of the Havasupai Falls in the bottom of the Grand Canyon. Calcium carbonate (lime) gives the water its blue-green cast and causes the travertine formations to build up. Only a month later, a flood roared through the falls, broke off the travertine veil and radically changed the appearance of the falls. This image is actually a composite of four photographs stitched together to create one.
