About the MSS - Dedicated to the study,exploration, and conservation of caves.

The MSS is the Minnesota chapter, or grotto, of the National Speleological Society (NSS). We are a non-profit MN corporation and have no paid staff, all our activies and programs are the result of the many dedicated volunteers.

MSS membership consists of many different people from all walks of life. Our membership include both people involved with karst professionally (geologists, engineers, etc) and people whose hobby is caving.We have members that are underground every weekend and we have members that never go caving.
