When compared with fluvial geomorphology, it is evident that the present state of karst geomorphology is one of minimal understanding and sophistication. For equivalent lawfulness to evolve in karst geomorphology, it is imperative that some hypothesis of karst formation and distribution be universally accepted. This study addresses the utility of an overriding hypothesis that the spatial distribution of karst depressions results from geomorphic processes which contain random or quasi-random components. The spatial variation of karst surface depression development is considered within the framework of macroscopic randomness of geomorphic process. To operationalize the stochastic model, three alternative hypotheses are assessed with quadrat methods at the .20 level of significance for their plausibility of being responsible for the spatial distribution of karst depressions on the Blue River Limestones in the unglaciated portion of the Mitchell Plain of south-central Indiana. Data for the analysis were collected from 7.5 minute series U. S. Geological Survey topographic quadrangles. Results of the analysis indicate that two mutually independent, non-equally important random spatial processes of cavern roof collapse and surface corrosion are conceivably responsible for the spatial distribution of karst depressions in the unglaciated Mitchell Plain.
