For decades, the term “pseudokarst” has been used for a diversity of landforms, evolved in various types of commonly insoluble, as well as chemically soluble rocks, sediments, and soils. There is a need to restrict the usage of the term. Morphology, genetic conditions, and the hydrological function were used as criteria in the evaluation of the problem. It is proposed that only processes and forms involving predominantly piping and thermokarst be termed pseudokarstic. Collapse depressions in non-soluble sediment karst-cover, where piping, did not play an important role, are karst-related features. No justification exists for keeping “volcano-karst” as a viable geomorphological term. Nonkarstic honeycombed and (or) pitted terrains (with lava rock, caves, eolian blowouts, ice-surface depressions, and so on) are neither karstic nor pseudokarstic. Field work has shown that the “gravel-and-sand plain pseudokarst terrains” along the Mississippi-Alabama-Florida Panhandle Coast in fact represent Citronelle Formation surfaces dotted by relict eolian and covered karst-related depressions.
