I find that natural arches usually frame the surrounding scenery very well.  The photo above was taken from underneath Devil’s Bridge, near Sedona, Arizona.  I was fortunate to have just the right amount of clouds helping to fill the frame.

Cave Creek Canyon, in the far southeastern corner of Arizona, is named for all the openings that dot the canyon walls.  From far inside one of the larger openings, looking back into the canyon, I loved how this shot is framed.
