What is the ESSO Grotto?

ESSO is a local caving club (grotto) of the National Speleological Society (NSS). We are a family oriented grotto that caves locally as well as out of state. We practice and teach safe and conservative caving as well as other outdoors activities. ESSO was established in 1968. ESSO has many different committees that you can get involved in such as cave locations, trip planning, vertical, photography, land owner relations, fund raising, and more!. There are many great events through out the year like summer picnics, vertical workshops, surveying workshops, parties, as well as weekend and weeklong cave trips. ESSO does not require you to have a membership with the NSS, but strongly encourages it.  As one of the most active grottos in the nation why would you not want to join ESSO?  Join today!

Regular Member Dues are $15 a Year (Due Annually by the Christmas Party in December)

Family Member Dues are $25 a Year (One Voting Member in the Family)
