Karst and the USGS

Welcome to the USGS Karst Website. This website presents information on USGS research on karst aquifers, which are a vital groundwater resource in the United States. Here you can learn about past and current USGS karst research, with information on ongoing studies, publications, and key contacts for major karst areas. Click on an aquifer on the map below, or select one from a list of aquifers.

Loss of water from the Peace River through underlying conduit during low-flow period, May 2004 Loss of water from the Peace River through underlying conduit during low-flow period, May 2004. The Peace River in this area is characterized by shallow, sometimes exposed carbonate units, with karst features that vary in type and size and include sinkholes, subsidence depressions, dissolution pipes, and enlarged fractures.
