Check this out! Driving to work this morning I saw these and despite the -10 degree temperature, I had to stop and snap a few pics.
Light pillars are a reflection of the light off of ice crystals in the atmosphere. We don’t see them often here in Colorado so it was a pretty unique opportunity. Unfortunately I didn’t have a tripod with me and had to get to work so these are quick, high ISO shots but still very fun to see.
Taken in north Denver, the lights are coming from the Union Pacific Railroad yard.
