My picture is a "noonish" shot taken in upper Antelope Canyon up in Northern Arizona. It is a "slot" canyon, 10 to 20 ft wide and 50 to 70 ft deep. Carved into the sandstone by flash floods. Google it, Wikipedia has an article on it and quite a few pictures. There are two canyons; upper and lower, which is more dangerous to enter especially when rain is near.
