Sacred Mountain


Overlook Mountain

in Woodstock New York, may well be one of the most important and sacred mountains in our region. Since the mountain has entered human consciousness many thousands of years ago, it has served people in innumerable ways and has attained high status and recognition not just in the local community, but worldwide.

The mountain acts as a major gateway to the nearly one million acre Catskill Forest Preserve, offering the closest Catskill Mountain summit trail head to the New York City metropolitan area. Overlook Mountain is also the center of Tibetan Buddhism in North America and was recognized as a sacred site by the Iroquois Confederacy at the Council at Onondaga in 1979.

The ancient importance of Overlook Mountain is reflected in a Native American ceremonial stone landscape (CSL) present in Lewis Hollow. Consisting or stone constructions, subsurface hydrological features, and effigies with a connections to the constellations, these archaeoastronomy and landscape archaeology features represent unique resources of cultural significance. The research, identification and protection of such resources as sacred sites, is inherent in OMC’s core mission.        

It’s time Overlook Mountain is honored and protected in a way that reflects its unique status and the immense contribution the mountain has made to humanity. The Overlook Mountain Center (OMC), through promoting cultural history, environment awareness, and community through collaboration, will act as a permanent human reflection of the mountain, honoring Overlook; the mountain that has given so much, to so many, in so many ways, for so long. OMC will create programming, exhibits and experiences that celebrate all aspects of Overlook Mountain, its’ past, present and future.

Mission Statement

OMC, a NYS educational nonprofit formed in 2013, promotes awareness and understanding of the relationship between Overlook Mountain and the human populations that have encountered it throughout time. OMC creates programs, exhibits and tours to educate, experience and celebrate all aspects of Overlook Mountain and its ecosystems.

Projects & Goals






Oversee the stewardship, conservation and preservation of the 37 acre upper Lewis Hollow Mantiou Hossennesh (spirit stones) site on Overlook Mountain in Woodstock, NY, containing cairns, “great” cairns, serpent effigy walls, springs and a possible Draco constellation petroform.  

This has been made possible thanks to funding secured by the Overlook Mountain Center, from a local private family foundation and other contributors.

 Oversee the transfer on the Lewis Hollow site property to an entity that will protect the site, the Manitou Honnessech (spirit stones) and the land they exist on, permanently, forever and in perpetuity.  

Conduct interpretive hikes that will lead visitors through the property, highlighting and explaining the site history, features and artifacts in their proper cultural context.

List the upper Lewis Hollow Property on the National and State Register of Historic Places as a sacred Native American Ceremonial Stone Landscape (CSL). This unique, one-of-a-kind property was Catskill historian Alf Evers backyard. The flora and fauna, along with the mysterious man-made stone constructions, have been the source of study for not only historians, but ecologists, biologists hydrologists, and archaeological researchers as well, all seeking to understand the various site features in their proper cultural context.


Create outdoor, experiential education programs related to landscape archaeology and archaeoastronomy.

Organize programs, lecture, workshops and seminars promoting and protecting a healthy environment, diverse culture and strong community, through interaction with Manitou Hassanach (spirit stones) present on Ceremonial Stone Landscapes on Overlook Mountains and elsewhere in our region.
