"Things You Wouldn't Know If We Didn't Blog Intermittently."
As a geologist in the oilfield of North Dakota we see an abundance of these when the conditions are right from the abundance of flares......
So cool. I don't often seen these, but do frequently spot sundogs and associated arcs.
I saw these on Christmas Eve heading south from Plattsburgh, NY. I was on the interstate and the pillars were coming from the headlights of the on coming cars. You could see them for miles, even around all the bends and hillocks of the road. Quite an amazing sight!! I've seen them before, but that was the most dramatic I've encountered.
