I haven't been to Morrison's since last March ice dive. But I can say that it is not uncommon that the holes wouldn't freeze back up. Just because people would continuously cut in the same area, it never gets a chance to be much more then push the ice chunk out the way. In fact last year when we went to do it had a hard time finding a decent area to cut that was solid enough around to support our big group. AT the shallow entrance guys would just walk in and break it as they walked until deep enough to go under
As sad and horrible this is, I sure hope it doesn't come down on Mrs. Morrison. You would never find a sweeter old lady that takes care of every diver that comes to enjoy her property.
