This was taken in the Lower Antelop Canyon in Page, Arizona. The lower antelope canyon is an underground canyon. The rocks that build the side walls get different colors depending on the position of the sun in the sky. Did not get much time in there to photograph, but a totally amazing place to see and photograph. Would recommend a visit to this place. This is less commercialized than the Upper Antelop Canyon and you can spend time at your leisure here unlike the Upper Canyon. This was the best I could get in the short time I spent there.
