This underground lake lets visitors take a trip back in time

Summer means it's time to plan the family vacation, and while many will be flocking to beaches and lakes, one peculiar location in Missouri allows visitors to travel back in time.

Located just 60 miles south of St. Louis, the Bonne Terre Mine is one of the world's largest mines and was used more than a century ago. The mine shut down in 1962 and was flooded with groundwater, creating a billion-gallon underground lake filled with crystal-clear water.

Once visitors are done exploring the vast underground caves, there's an entire additional world to experience underwater.

With 88 different passageways, the waterlogged ghost town serves as a time capsule of the era and is a diver's dream.
