National Speleological Society is the primary national cave and karst organization of the United States, with over 10,000 members and 250 affiliated grottos. The NSS does more than any other caving organization to study, explore, and conserve cave and karst resources; protect access to caves; encourage responsible management of caves and their unique environments; and promote responsible caving.

NSS Internal Organizations, Regions, and Sections

Check out the NSS Internal Organizations page for other types of organizational structures associated with the NSS. In almost every state containing a number of caves, groups of NSS cavers actively maintain data on the caves and pursuing further exploration. They are often organized into NSS Regions that work together in projects and pool resources.

Only a few of these caver groups have asked for NSS charters as other types of Internal Organizations; others are recognized but are independent. 

There are, for example, a number of NSS Sections, as well -- specialized sections affiliated with the NSS. These are made up of cavers with specialized interest in caving. Examples are Cave Diving, Geology and Surveying. Most important is the NSS Conservation & Management Section. This section is dedicated to reserving and protecting caves and karst for cavers, scientific research, and the general public; it represents one of the most important goals of the National Speleological Society.

The TSS is an Official NSS Project, one of the established national repositories of US cave data.

THE NATURE CONSERVANCY The Nature Conservancy is the leading global conservation organization focused on protecting ecologically important lands and waters.

The TCR provides an eclectic weekend of cave-related education and training activities, fun and games, equipment and publication sales, extreme good socializing and fellowship, and the caving world's best feed. Information on the TCR can be found in the Texas Caver and on their website.
