[edit] 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 51 kilometers (32 miles) 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).
[edit] 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).
[edit] 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. Notable HERI students include Joel Despain (International Expeditions Chair, National Speleological Society) and Patricia Kambesis (former President, Cave Research Foundation).
[edit] Background
Glennon is a geography Ph.D. student of Dr. Michael Frank Goodchild at the University of California, Santa Barbara. Goodchild is a pioneer in Geographic Information Science and discoverer of Castleguard Cave, Canada's longest cave. Glennon received a Master of Science in Geoscience from Western Kentucky University, 2001, and Bachelor of Science in Park Administration from Texas A&M University, 1994.
