Spilling Thought: Picture yourself under the #NorthernLights at White Mountains National Recreation Area in #Alaska. Bob Wick -- who caught this dramatic green display -- describes his first experience photographing the #auroraborealis: “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 #nightsky that compares!" Photo by Bob Wick, @mypubliclands by usinterior
