Build Up

Viewed from the windward side, the shelf ice along the Michigan City, Indiana lighthouse and pier, virtually takes over the structure.  Rising at least 15 feet above the water's surface, one can touch the catwalk, and at some points, climb right up.

Here, the thickness and size of the ice is evident due to the hole in the ice seen in the foreground. Following some snow and wind, this hole could be completely covered over by a thin layer of snow and ice.  A person can unknowingly walk on that thin ice and plunge to the icy water below.

Here, we were safely over the concrete pier, and in no danger of falling through the shelf ice.
