Discoveries and research

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. The combined cave system is long. The cave is hydrologically connected to Mammoth Cave---the world's longest cave. Glennon also was involved in the discovery of one of the largest cave chambers in Kentucky.

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.

Hoffman Environmental Research Institute (HERI)

With Dr. Chris Groves, president of the Cave Research Foundation, 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

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.
