Geology lecture at Slate Valley Museum

The Slate Valley Museum will welcome Helen Mango, Professor of Geology and Chemistry at Castleton Geology LectureState College, to present “700 Million Years of Mountain-Building: A Geologic History.”

The lecture program, which will take place on Thursday, April 23 at 7 p.m., is part of the museum’s week-long celebration of Earth Day.

The northern Appalachian Mountains record two billion years of plate tectonic action. Mountain-building, erosion, metamorphism, volcanism – all have shaped the geology that we see around us today. In this talk, Mango will guide visitors through 700 million years of that history, describing the formation of the Adirondacks, the Green Mountains, the Taconics, and how they all fit together.

“This geologic history is incredibly relevant to the stories we tell at the museum,” notes Education & Research Coordinator Bob Isherwood. “The slate here formed as a result of plate tectonics. The broader geologic history that Helen will share provides a great context for our visitors to understand the forces that helped shape our region.”

Mango completed her undergraduate work in Geology at Williams College. She also earned masters and doctoral degrees in Geology from Dartmouth College. She has been teaching at Castelton State College since 1991.

The cost to attend the lecture is $5, which also includes admission to visit and explore the museum. Slate Valley Museum members may attend for free.

The Slate Valley Museum is located at 17 Water St. For more information visit www.slatevalleymuseum.org or call 518-642-1417.
