William B. White, Ph.D. and Professor Emeritus at Penn State’s Dept. of Geochemistry, is one of the world’s great authorities on cave formation and cavern features.

The Arizona Geological Society will host Dr. White’s presentation, ‘The Science of Caves and Cave Contributions to Science’.  This hour-long presentation, with 15-minutes for questions, will paint a ‘broad brush overview of cave sciences in the 21th Century.’
