A mid-morning rainbow

Rainbows always occur near sunrise or sunset, because the Sun has to be low. I have seen a spectacular circular rainbow while driving across the Bridge of the Gods in the Columbia River Gorge. The height of the bridge allowed the circle of the rainbow to continue all the way around But I photographed this rainbow today after 10:30, a day when sunrise was just before 8 am. I don't think this is any sort of special atmospheric conditions; must be the limit of Sun height. Click to see the photo full-size.
