The National Speleological Society (NSS) is an organization formed in 1941 to advance the exploration, conservation, study, and understanding of caves in the United States. Originally headquartered in Washington D.C., its current offices are in Huntsville, Alabama. The organization engages in the research and scientific study, restoration, exploration, and protection of caves. It has more than 10,000 members in more than 250 grottos.[2]
Since 1974 there has been a cave diving section of the society.
The Speleological Society of the District of Columbia (SSDC) was formed on May 6, 1939 by Bill Stephenson. In the fall of 1940, the officers of the SSDC drafted a proposed constitution that would transform the SSDC into the National Speleological Society. On January 24, 1941, Stephenson sent a letter to all members of the SSDC announcing that "on January 1 the Society was reorganized as a national organization."[3] The New England Grotto was the first NSS Grotto. It was chartered in 1941 with Clay Perry as president and Ned Anderson as vice president.[4]
On February 6, 1974, a pioneering cave diver named Sheck Exley became the first chairman of the Cave Diving Section of the National Speleological Society.[5] [6] The new section began with 21 members in 10 different states.[5]
The NSS produces a number of publications, including:
The NSS's list of long and deep caves was kept until 2022 by surveyor and cartographer Robert Gulden.
The organization is currently divided into 11 regions:
Within these regions are local chapters known as grottos. The grottos carry out the local-level recreational and conservation-related business of the NSS. They generally function as the local NSS chapter/club. Many Grottos however operate in areas outside of their local area, with many operating in several states.[7] Most Grottos also participate in Regions that are loose associations of Grottos.[7] Regions are also an internal organization of the National Speleological Society.[7]
Grottos are required to meet certain organizational requirements as outlined by the National Speleological Society. These include:[8]
The NSS hosts a yearly convention, which is generally held in June. Grottos take turns hosting the convention.
