Situated along the Helderberg Escarpment, discover one of the richest fossil-bearing formations in the world. While protecting six miles of limestone cliff-face, rock-strewn slopes, woodland and open fields, the park provides a marvelous panorama of the Hudson-Mohawk Valleys and the Adirondack and Green Mountains. We offer a variety of field trip and outreach programs. Link to Field Trip Brochure: https://parks.ny.gov/documents/parks/ThacherFieldTripBrochure.pdf
