Geology of the Hudson Valley

September 25, 2022 @ 11:00 am - 1:30 pm

Orange pumpkins on a craggy boulder below Ravens Rock in Sleepy Hollow, New York

Join environmental educator, Kim Fendrich, on a journey through time.

Learn about the geologic history of this area and observe evidence of tectonic activity, glaciation, weathering, and erosion throughout the Preserve. You will begin with a demonstration to put Earth’s 4.5 billion year history into perspective, followed by discussion and then a short walk to get up-close and personal with some rocks along the Sleepy Hollow trail. You will walk about 2 miles in total.

Meet in the Rockefeller State Park Visitor’s Center courtyard.
