I learned about this in my geography class just last December. Neat to see pictures of it!
Mammoth cave is one of the largest caves in the world.US/Mex It is unknown exactly how deep it is because some of it has not been explored yet.
I hope you have fun visiting them this summer.
We took one tour that lasted about 3 hours and covered about 2 1/2 hours.It went down almost 200 feet.
