Solution zones are of two kinds: (1) tabular bedding-plane channels and (2) enlargements of near-vertical joints. Most of this solution has occurred below the water table. Bedrock solution is controlled by (1) lithology (tabular zones are in limestone layers, and vertical zones widen in limestone and narrow in chert layers) and (2) structure (initial ground-water circulation was through joints, and the vertical solution channels are aligned in conformity to joint patterns). Widening of vertical solution zones results from lateral extension along limestone layers and the collapse of intervening chert layers. The jumbled character of the residual chert and clay filling is a reflection of this mechanism. One major vertical solution channel, formed by the coalescence of enlarged vertical joints along the flank of a slightly anticlinal structure, is 70 to 100 feet wide at the bedrock surface (elevation 270) and narrows to extinction at elevation 70. The presence in this solution zone of sand from the Ripley formation, which has since been eroded from the immediate vicinity, indicates that extensive erosion has occurred since solution began—i.e., the solution has been a continuous process of long duration.
