Product Description:

In their exploration of the Carlsbad Cavern of New Mexico, expert geologists Carol Hill and Dave Jagnow discover blocks of mineral that according to well-known geology theories should not be there. This amazing find is the subject of MYSTERIOUS LIFE OF CAVES. Armed with new evidence, the two geologists go on a quest into the deepest underground caverns to support an idea that microbes and toxic hydrogen sulfide gas are the new culprits of cave formation.
