We had a snow storm last week with freezing temperatures at the start of the week. The fountains near Araphoe Station were pumping warmer water. With the cold air, this created mist around the fountains of water.
The nearby office building reflected light back into the fountains, highlighting the mist.
A couple of days later, I noticed the shadows cast on the marble-clad building where I work.
I made this image to include a tree with it’s shadow on an adjacent building.
