The Oregon High Desert Grotto is an internal organization of the National Speleological Society. We are dedicated to the study and preservation of caves.

 

Membership in the Grotto is $15 a year and comes with an invitation to the Yahoo! Groups forum, access to the Grotto library, issues of the Oregon Underground newsletter, and information on yearly caving activities and trips.
