Light pillars, An Incredible Optical Phenomenon !!! Sometimes during very cold weather, vertical columns of light beaming directly upwards are visible. These are called light pillars and are created by the reflection of light from ice crystals with near horizontal parallel planar surfaces. The light can come from the Sun in which case the phenomenon is called a sun pillar or solar pillar. Light pillars are typically seen in polar regions.

Solar Pillars are caused by sunlight reflecting off the bottom of stacked plate-like ice crystals in the upper atmosphere. They are not considered that rare, but really strong, clear, vibrant ones like this one seen in Canada, are a real treat. Read more: www.dailymail.co....
Light PIllars, Walter Tape (Alaska Fairbanks) May 2006 flat fluttering ice crystals may form near the ground in a form of light snow, sometimes known as a crystal fog. These ice crystals may then reflect ground lights in columns not unlike a Sun-pillar.
