This morning I came across another thing new to me which occurs during very cold weather. Light Pillars! Most of the time these vertical lights coming down from the sky happen in places in northern climates such as Norway, Canada, Wyoming, Russia. Very rare in our part of the woods, but last week was so cold, Light Pillars became visible over Scott Air Force Base/ Mid-America Airport. I saw the photo accompanying the local light pillars, but it is very copyrighted so I could not download it which is only fair to the photographer.
But here is a link to that photo.
And, here is a stock photo of light pillars from Laramie, Wyoming.
How cool is this?
