Karst development is a gradual process of carbonate dissolution over time, and epikarst and sinkhole features are often near-surface manifestations of this process. In south-central Indiana, thin soil cover over dissolving bedrock provides little protection from increasingly fragile terrain in some areas. Such areas are susceptible to subsidence and collapse. Understanding the controls on karst development through statistical modeling provides a basis for predicting areas likely to develop sinkholes in the future.
