About the preserve

John Ackerman established the Minnesota Cave Preserve in 1989 to preserve, study, protect and to promote conscientious exploration and conservation of our unique underground wilderness.

From the beginning, John recognized the need to protect the fragile and timeless environment, both above and underground. Conservation has always been a prime tenet of the Minnesota Cave Preserve.
