Sheffler's Rock Shop/Geode Mine, MO
FYI, as of 10/20/13, Sheffler's is still open. Accurate directions from St. Louis: Proceed north on Rt. 61, take Keokuk/rt. 61 exit, turn left off exit ramp, cross freeway bridge, turn right on access road, proceed about 1/2 mile north. Look for signage and several tractor/trailers on lot marked "Fossils/Geodes." Call before showing up. Usually closed on Sundays, but may open on appointment.
