What is ESSO Grotto?
ESSO Grotto is the Eastern States Speleological Organization. ESSO is the regional chapter of the NSS (National Speleological Society) and is one of the most active caving organizations in the nation. ESSO represents the NSS in the tri-state area of Kentucky, West Virginia and Ohio. Our grotto is one of over 200 local chapters, or grottos, located around the country, represent the bulk of the internal organizations of the Society. Grottos usually conduct regular meetings and serve to bring cavers together within their general areas and coordinate activities. Many grottos publish a newsletter as a regular part of their programs such as ours, the ESSO Bee. In other words… ESSO = Uniting force, bringing cavers together in a safe, organized manner.
