Informational discussion and mailing list for the Mid-Appalachian Region of the National Speleological Society.

The MAR is an association of caving clubs and grottos within the general geographic area, or "region", of Pennsylvania, Maryland, Delaware, and New Jersey. MAR, also an internal organization of the NSS, is dedicated to the principles of the NSS, to promote fellowship among its members, and to advance the science of speleology.

This list is open to anyone, however, it is primarily focused for individuals belonging to a grotto within the MAR Region.
