DESCRIPTION:The epigenetic model of speleogenesis was a product of observat
 ions and measurements in caves of Indiana and Kentucky. In his transformat
 ive work starting in Indiana\, Art Palmer combined the mode and pace of re
 charge enhanced with soil carbon dioxide and the physical distribution of 
 porosity in the host rock as a deductive model for the shape and distribut
 ion of resulting caves. The predictive power of Art's synthesis was an imp
 ortant step to understanding the evolution of caves.\n\nTransformative sci
 ence and comprehensive models are laced with anomalies. In Kentucky\, seep
 s of petroleum in caves and unusual passage morphologies\, secondary miner
 als\, and rock textures revealed hypogene speleogenesis from sulfide oxida
 tion. Soon\, similar hypogene influences were also detected in Indiana cav
 es. What is now clear is that cave evolution is polygenetic and multigener
 ational and may include hypogene cave development overprinted by epigeneti
 c processes. Caves have formed at multiple stages throughout the history b
 edrock.\n\nWhat is also apparent is the association of caves with geologic
  structures. At the largest scale\, regional structures position the carbo
 nate outcrop. At localized scales\, fractures and faults are pathways for 
 meteoric recharge and can guide groundwater movement and the orientation o
 f cave passages. Faults are also preferred pathways for rising basin fluid
 s and thus the locus of hypogene speleogenesis. Geochemistry studies of gr
 oundwater demonstrate the influence of sulfur in some caves of the Mitchel
 l Plateau. Analysis of drilled cores\, geologic mapping\, LiDAR data\, and
  cave maps characterized extensions of the Mount Carmel Fault zone in sout
 hern Indiana.
