There's always "one that got away"; back when I was in college I looked outside and saw what looked like an upside-down, hanging rainbow. Turns out it was a circumzenithal arc. Didn't have the camera.
Most of these pictures are from the last two years; the sun pillar photos are the most recent: from this New Year's Eve. We spotted them on our drive home from Grandma's house... What an amazing way to end the year! It felt like God's reassurance that he's aware and still in charge.
(For a music-backed experience, play Desert Symphony while watching the pictures. Yeah, their videography upstages my pictures. Enjoy them both. )
