“Tsunamis in Syracuse?”

Bryce Hand, Ph.D.

About the talk
Geologists tend to use “catastrophic” events like meteorite impacts only as a last resort (and Professor Emeritus Bryce Hand is one of them). However, in his presentation Professor Hand will argue that the signature of just such an event can be found right here in Onondaga County! The six-foot-thick layer we call the Clark Reservation Limestone seemed like an anomaly from the moment he met it in 1969. Over the next couple decades he became convinced that this limestone must have been emplaced by a tsunami, but one caused by an event so special that the usual triggers—earthquakes, submarine landslides, extreme weather events—wouldn’t suffice. Then, in 1993 when he attended the Geological Society of America meeting where Yngvar Isachsen (distinguished geologist with the NY State Geological Survey) argued that that the seven-mile-diameter circular structure at Panther Mountain, in the Catskills, was an astrobleme—the signature of a buried impact crater.

About the presenter
Bryce Hand received his Ph.D in geology from Pennsylvania State University in 1964, and taught geology first at Antioch College, and then at Syracuse University for 35 years. His research focus was sedimentology. Bryce is now a professor emeritus of geology at Syracuse University, and has been a member of CNY Skeptics for 15 years.
