A 200 foot tower of stairs allow visitors touring Silver Dollar City's Marvel Cave to descend from above ground heat to near steady 60 degree temperatures during a one hour tour as people find ways to cool off at Silver Dollar City Theme Park in Branson, MO on July 28, 2023. This first opening is called the Cathedral Room, one of the largest cave entrance rooms in North America. The popularity of cave tours has increased due to the summer heat.
