I am a lake watcher. Yesterday there was snow on Lake Michigan here in West Michigan. Today people should stay off of piers because of the high waves. Usually, ice begins to form on the shore by Thanksgiving. I am watching to see if it does this year.
The title of my book, The Dynamic Great Lakes, is about how and why the five Great Lakes change. They are always changing. There is a new edition out for 2010 with updates.
