These columns on the University of Michigan campus are actually outlets for the school's heating and cooling system. There are many of them and they are often used as convenient places to post flyers, posters, and other ads.

Hi lsloan0000,

Thank you for a comment. Right. This is one of vents for several mile long tunnels of air control. By this huge heating system, I can feel warm when I jog through Ann Arbor downtown area in under-zero degree winter.
