Slice of Life: Metra’s Slow Motion Snot
Scenes like this are pretty common in Chicago in the winter. Except, this isn’t winter. This photo was taken in July. The icicles aren’t ice, they’re mother nature’s own form of mineralized snot, dripping ever so slowly underneath the Union Pacific tracks that carry Metra trains into the Ogilvie Transportation Center (500 West Madison Street).
Lots of Chicago’s old bridges have these stalactites, and in theory, it’s possible to tell how old a bridge is by their length.
