John Boyd Thacher State Park Earns National Natural Landmark Designation

Dec 14, 2023

(Voorheesville, NY) – John Boyd Thacher State Park proudly announces its National Natural Landmark designation by the National Park Service. Under the stewardship of the New York State Office of Parks, Recreation, and Historic Preservation, the park showcases the distinctive ridge of the Helderberg Escarpment, which, in addition to its scenic allure, stands as a living testament to the geological evolution and ecological diversity of the region. The National Park Service’s announcement is available here.

"I extend heartfelt thanks to the National Park Service and Secretary Deb Haaland for acknowledging the geological marvel of Thacher Park,” State Parks Commissioner Erik Kulleseid said. “Our commitment to stewardship of this beautiful land remains unwavering, and this recognition bolsters our determination for years to come."

Established in 1962, the National Natural Landmarks Program selects areas as the “best example” of a biological community or geological feature based on condition, character, rarity, diversity, and scientific and educational value. Currently, there are over 602 such sites nationwide.

The park's cliff face is a geological mosaic, narrating Earth's history over 63 million years. Notably, layers from the Middle Paleozoic Era mark a pivotal era of marine expansion and the emergence of terrestrial life, with fossils like trilobites, brachiopods, and crinoid stems found throughout the park.

Moreover, with over a century without logging, the park hosts untouched hardwoods of the Eastern Deciduous Forest, contributing to a diverse ecosystem with 21 distinct ecological communities and rare plant and animal species. Featuring 40 caves and 17 springs, the park offers a unique natural experience.

Enthusiasts eager to delve into Thacher Park's rich geological history are encouraged to visit. The park, open year-round, boasts a visitor center with educational exhibits, a nature center offering programs for children, and over 25 miles of trails, including the renowned Indian Ladder Trail along the cliff face and past picturesque waterfalls.

The park, located 12 miles west of Albany, is further enhanced by the Shido Foundation endowment, which supports a geology educator, offering specialized tours and programs focused on the park's unique geology.
