Northwestern Arkansas is well known for its karstic features. Karsitc features include sinkholes, conduit springs, and large caves. A sinkhole is an oval shaped depression that is formed from the dissolution of carbonate bedrock. These sinkholes are important because this is where water recharge enters the aquifer directly.
