A Sun Pillar From Tucson

Tonight after sunset we were treated to a Sun Pillar in Tucson. Sun pillars are caused by light reflecting off of ice crystals high in the atmosphere. I was out photographing sunset (weak green flash tonight) and was starting to put my camera away. I turned around to look west again and that’s when I saw the pillar. Glad I wasn’t in too big of a hurry to get out of there!
