Pillars to the zenith  

Pillar image index
Lights pillars to the zenith. Lauri Kangas (site) saw these exceptionally tall light pillars in Ontario, Canada in January '04. " I managed to get a few images of light pillars that were so tall they converged overhead at the zenith. It was bitterly cold at -24C but there was no wind and there was a drizzle of ice crystals falling from the sky." The light pillars appear to converge towards the zenith because the plate shaped ice crystals producing the reflections of lights on the ground are at different heights in the atmosphere - more here.  Images ©2004 Lauri kangas, shown with permission.
