Photographer Sarah Bethea was exploring inside a glacier cave in southern Iceland when the setting Sun suddenly lined up with the cave entrance, making a wall inside the cave suddenly look like glowing amber.
The Oregon-based photographer witnessed this phenomenon in December 2017. It’s said that the Sun only lights up the glacier cave in this way once or twice a year.
“The light of the sunset striking the ice made it glow like amber for just a few minutes,” Bethea writes. “I expected these ice caves to be beautiful, but this was quite a surprise. Nature never fails to amaze.”
