Magical Lake Wissota
When Rose is threatening to kill herself on the front of the Titanic, Jack decides to tell her a story. He speaks of a lake near Chippewa Falls that he went ice fishing on, Lake Wissota. This is a really interesting story because it makes no sense. At least, it didn’t make sense in 1912 when the Titanic was on the water. You see, Lake Wissota is a man-made lake that was created after the Chippewa River was dammed. That didn’t happen until 1918, a full six years after the Titanic sunk. So, either Jack Dawson is a time traveler, or he’s making up a baloney story to dissuade this pretty girl from killing herself. Come to think of it, both explanations are pretty reasonable.
