Details:
On my 04:30 a.m. drive home from comet chasing this morning, I just had to pull over and photograph the light pillars over a local gas station. From the Atmospheric Optics website (http://www.atoptics.co.uk/halo/lpil.htm):
"Columns of light apparently beaming directly upwards from unshielded (and wastefully polluting) lights are sometimes visible during very cold weather. Plate shaped ice crystals, normally only present in high clouds, float in the air close to the ground and their horizontal facets reflect light back downwards. The pillars are not physically over the lights or anywhere else in space for that matter ~ like all halos they are purely the collected light beams from all the millions of crystals which just happen to be reflecting light towards your eyes or camera."
