Ozark National Scenic Riverways
— National Park Service, U.S. Department of the Interior —
Karst is a special type of landscape that is formed by the dissolution of soluble rocks, including limestone and dolomite.A karst topography is characterized by rolling hills, deep hollows springs, caves, sinkholes and tunnels.Rain water, seeping through soil, becomes slightly acidic. Water penetrates cracks and joints, slowly dissolving porous limestone bedrock. Through time, cracks and joints enlarge, creating a vast underground drainage system.
Big Spring carries 173 tons of dissolved dolomite bedrock away in a day. Over one year, this would equate to a new passage about 11 feet wide, 12 feet high and 1 mile in length.
