If you were outside Tuesday morning, you were treated to a beautiful sunrise. There were pretty pink, red, orange and yellow hues in the sky. You may have also noticed what appeared to be a vertical beam of light extending from the ground up into the sky. This is an optical phenomenon we call a light pillar. A light pillar appears when sunlight is reflected off of falling ice crystals within high-level clouds. Also called sun pillars, these often occur in cirrostratus clouds which are at an altitude above about 20,000 feet.
