ACCA members are part of a special group working to preserve one of the most unusual environments on Earth. Membership in the ACCA is open to anyone interested in protecting cave and karst resources. Membership dues and contributions go to support the ACCA, the American Cave Museum and ACCA educational and conservation programs.

The American Cave Conservation Association needs people with the vision to see how crucial underground resources are, for this and future generations. We need people willing to help us promote understanding through the development of facilities, programs and research designed to tell the story of caves, karst and groundwater and how a pristine environment benefits everyone in the long run.

ACCA is a non-profit environmental organization whose members, activities, and proceeds are dedicated to the conservation of caves and related resources across the nation and around the world.

The great successes achieved by ACCA during its 30-year history, particularly during the last 15 years, are a direct result of the integration of these five components: A Cave Museum, Cleanup Projects, Education Programs & Community Outreach, and Cave Gates Protecting Endangered Species & Archeological Sites.

We educate people about caves and karstlands so that these features and their resources can be conserved.

Our target audiences are those people who live in, work in, or otherwise use or enjoy karstlands..
Created on An Ecological Mandate

ACCA is concerned with all caves, regardless of their mode of origin or location. However, most caves are found in the earth's more water-soluble rocks such as limestone, dolomite, marble and gypsum.  The lands in which these types of caves are found are called karst or karstlands. 

In karst, there is appreciable groundwater movement through dissolved-out  openings in the bedrock; karstlands often have features such as sinkholes, sinking streams, springs, and sometimes caves.

Approximately 20% of the United States is karst.  In karst, the surface and the subsurface are intimately connected; cave and groundwater resources cannot be widely used without careful land use of the surface.  Simply put, clean caves and karst equal clean water.
