Caves In 1996, Glennon and Jon Jasper discovered an entrance to the
Martin Ridge Cave System,
Kentucky, and explored connections to nearby Jackpot and Whigpistle Caves (Groves, C.G. 1998). The combined
cave system is long (Gulden, B. 2005). The
cave is hydrologically connected to
Mammoth Cave---the world's longest
cave (Quinlan J.F. and Ray, J. 1989). Glennon also was involved in the discovery of one of the largest
cave chambers in
Kentucky (Yonker, R. 2003).
Geysers In 2002, Glennon led an
American expedition to
El Tatio Geyser Field,
Chile. The team produced the first comprehensive inventory and description of the geysers' behaviors. The resulting report concluded that the site was the world's third largest
geyser field (Glennon, J.A. and Pfaff, R.M. 2003).
Hoffman Environmental Research Institute (HERI) With Dr.
Chris Groves, president of the
Cave Research Foundation (2004-2006), Glennon cofounded HERI in 1999. The institute's mission is to study the
environmental and
geologic aspects of
caves and
karst landscapes. Headquartered at
Western Kentucky University, HERI's major scientific focus has been on the
karst issues of
China. ==Background==
