Multiple rainbows

In order to catch a glimpse of this intriguing optical phenomenon you need to be close to a body of water such as a lake or large river (in this case the Knik in Alaska). The primary and secondary bows comes from the usual internal reflections in water droplets in the air. The extra rainbows are due to reflections from the river and include both primary and secondary seta, though the latter is very faint.
