Photo of the Day: Fogbow arches over a dirt road

1534 of 1626

We have rainbows, moonbows, and yes, even fogbows. USFWS writes, "Fogbow centered on South Valley Road in Red Rock Lakes National Wildlife Refuge. Fogbows form in the same way as rainbows. A small fraction of the light entering droplets is internally reflected once and emerges to form a large circle opposite the sun. Fogbows are formed by much smaller cloud and fog droplets than the raindrops that form rainbows."
