Many questions about eavern origin and subsurface water flow through limestone must ultimately be answered by a consideration of the mechanisms whereby initial fractures within limestone become enlarged into caves by the subsurface water flowing through them. Among these problems are: (1) the processes causing selective enlargement into cavern
