Product Description: 

In the mountains of the southern United States, under a quiet river, there is a tiny crack in the earth that gushes forth millions of gallons of spring water daily. It is an ancient and powerful cave - cold, deep and very narrow. The cave is so restrictive that the divers cannot wear scuba tanks on their back as they explore. Welcome to the world of sidemount cave diving. Travel along with expedition divers as they face some of the toughest diving conditions on earth in search of places no human being has ever been before. Experience what exists beneath the Ozark Mountains.
