What Have We Been Up To? 

who are we?
We are amateurs and academics, people from all walks of life drawn together by our common interest in the
world beneath our feet.  This interest goes beyond the
casual cave trip.  We invite
you to join us as we satisfy
our curiosity about the how
and why, the where and
what of Missouri caves, karst, and springs - learning their secrets, recording them, and working to preserve both the caves themselves and our knowledge about them.
