The National Karst Map program is a collaborative effort facilitated by the National Cave and Karst Research Institute, and coordinated by the U.S. Geological Survey. Partners in this program include State Geological Surveys, universities, and private groups. The national map currently available though this website was produced by the USGS in 1984. An updated and improved national map of karst areas is under development. Links to interim products will be added as they are produced.
