Picture yourself under the Northern Lights at White Mountains National Recreation Area in Alaska. Bob Wick – who caught this dramatic green display – describes his first experience photographing the aurora borealis: “It was interesting to see how dynamic and fickle the display was, going from a dim glow to bright, dancing molten light pouring from the skies in a matter of 30 seconds. I have never seen or photographed anything in the night sky that compares!“ Photo by Bob Wick, @mypubliclands.
