Nevada tufa is a natural rock that formed 10,000 to 20,000 years ago when half of Nevada was covered by an inland sea called Lahontan.  The tufa formed on the sea floor when natural mineral springs came into contact with saline sea water and the dissolved minerals precipitated out of solution.  The minerals, calcium carbonate and silica, fell to the sea floor and solidified in horizontal layers in a process similar to that which forms stalactites in caves.  Spring water jetting upward through the sea bed layers formed the holes in this bizarre and unique formation.
