Elephant Rocks State Park
One of the most curious geologic formations in Missouri is found at Elephant Rocks State Park. Giant boulders of 1.5 billion-year-old granite stand end-to-end like a train of circus elephants. Many of the elephant rocks lie within the seven-acre Elephant Rocks Natural Area. This natural area is recognized for its outstanding geologic value. http://www.mostateparks.com/elephantrock/geninfo.htm
