Stygian Grotto

Stygian Grotto is a non-profit organization located in St Peters, Missouri. Founded in 1980, we are an affiliate organization with the National Speleological Society, the Missouri Speleological Survey, the Missouri Cave and Karst Conservancy and Missouri Stream Teams. Our purpose is to explore, research, educate and conserve the flora and fauna of the caves, springs and streams in the Mississippi Valley Ozark Region.

Take nothing but pictures, leave nothing but foot prints, kill nothing but time
