Spilling Thought: We're counting down our list of top 5 outdoor adventures to add to your #bucketlist in 2015. No. 1: Watch the #NorthernLights dance overhead. The #AuroraBorealis puts on a spectacular show -- glowing, shimmering and swirling in the sky above. While it’s easier to see the Northern Lights in high latitudes like #Alaska, strong bursts of this natural phenomenon can sometimes be seen from America’s #publiclands in lower 48. Daniel A. Leifheit (@danleifheit) captured this photo of the the Northern Lights dancing across the starry sky over #Denali #NationalPark in Alaska. National Park Service photo. by usinterior
