So... how do they navigate?
I found this pair of photographs on Gab yesterday, showing a lighthouse on Lake Michigan near St. Joseph during and after a winter storm. Clickit to biggit.
I've seen similar photographs before, of course, as I'm sure have most of my readers. However, I'd never thought about one obvious question. If the lighthouse is required by ships on the lake for safe navigation, what happens when it's shrouded in ice and its light can no longer be seen? Is waterborne traffic suspended until it defrosts? Is, there, in fact, any waterborne traffic on the Great Lakes during the winter months, or does everything come to a grinding halt until the spring?
I have no idea of the answers, but I'm sure my readers in that part of the world can tell us. Please let us know in Comments. Thanks!
