Ha Ha Tonka Karst
This area is one of Missouri's best examples of a complex karst site formed from the collapse of a major cave system. Down-cutting streams intersected, collapsed and eventually destroyed the cave system which once existed here. The collapse chasm is referred to as Ha Ha Tonka canyon. A large spring, several sinkholes, several caves and a natural bridge are prominent karst features. The area lies within the Upper Ozarks Section of the Ozark Natural Division. An interpretive trail guide provides information on the terrestrial and geologic natural features found along the nature trail.
