Shot taken of Barton Dam in Ann Arbor, Mi on a cold (almost) winter morning. You can see the ice forming on the wall of the building as well as along the top of the dam.
I really like this dam. It was designed by University of Michigan Dean of Architecture Emil Lorch and built in 1912. See reference
Another interesting item is that there used to be a staircase running along the side of the building. See this image for details
