21 June 2009 | Cathedral Rock, Sedona Arizona. 

This distant view of Cathedral Rock near Sedona, Arizona was taken at sunrise on June 21, 2009 (summer solstice) from the top of West Twin Butte. It shows the shadow cast by the summit of East Twin Butte directly in line with the saddle of Cathedral Rock. This sundial effect must have been known to prehistoric people living in the area as a significant archaeological event. (Photo by Paul Lindberg.)
