Mississippi Valley Ozark Region

In addition to ourĀ  other associations, many Grotto members are also members of the Mississippi Valley Ozark Region (MVOR). The MVOR is a regional caving organizion that consists of cavers primarily in the state of Missouri and it’s surrounding states, including Illinois, western Kentucky, western Tennessee, eastern Oklahoma, northern Arkansas, southern Iowa, eastern Indiana and eastern Kansas. The MVOR holds meetings twice a year, spring and fall. The meetings are rotated with-in the various states and are hosted by the various grottos within the region.


The Grotto has been an affiliate of the National Speleological Society(NSS), since 1964.

More locally, the Grotto is one of many grottos associated with the Missouri Speleological Survey (MSS) and the Illinois Speleological Survey (ISS). Both of these organizations are designed to promote cave and karst awareness of the cave resources and information for their respective states.
