This saying likely stems from the lake's notoriously treacherous waters, which have claimed countless lives over the years due to its size, depth, and unpredictable weather. Many shipwrecks and other accidents have occurred on Lake Superior, and many of the victims have never been recovered.
However, it's important to note that this is a figurative expression, not a literal truth. While it's true that some bodies from Lake Superior have never been found, it's not because the lake is magically holding them captive. It's simply due to the vastness and depth of the lake, making recovery efforts challenging.
