I was visiting Iceland with a friend and we decided to take the Ice Cave Tour for a bit of an adventure along the Golden Coast. It was a bright and sunny day so there were rainbows aplenty refracting off the ice. This shot, in particular, was taken deep inside the cave where there was a large opening above us, directly below the sun, thus causing the beautiful refraction you see in the picture. Submitting this here because a friend suggested I should.
