This page provides links to some of Hans Bodenhamer's articles on the geology of Montana's caves.  Bodenhamer studied geology at Northern Arizona University and taught geology courses at Cochise County Community College, but most of his knowledge on cave geology is self taught and inspired from an intense interest in caves and their development.  Below is a map showing areas where Bodenhamer developed geological interpretations for some Montana caves.  Below the map are links to articles that correspond to areas on the map.  The photo above shows a thrust fault along which a passageway in Poia Lake Cave was formed.  Photo by Mike McEachern.
