|Whale Bow imaged by Gordon Pierce off the coast of Oregon in June '09. ©Gordon Pierce, shown with permission.
"The photo was taken at Boiler Bay which is located several miles north of the small Oregon town of Depoe Bay.
Two Gray Whales were just yards from the coastal rocks, skies were clear and the temperature was in the mid 50's with high humidity. The spout was all vapor and the rainbow lasted for about 5 seconds in the still air.
I have seen many rainbows over the years, but this is the first one created by a mammal."
