 Since 2012 Overlook Mountain Center (OMC) has endeavored to identify, protect, research and document the historic and prehistoric resources of cultural significance present at the Lewis Hollow Site on Overlook Mountain in Woodstock, NY. 

As an identified ceremonial stone landscape (CSL), we believe the site meets the criteria set by The United South and Eastern Tribes (USET), based on resolution no. 2007-037, regarding sacred ceremonial landscapes found in ancestral territories of United South and Eastern Tribes, member tribes.
Below is a chronological list of the evidential reports and documents, as well as a brief description of each item and a link to it. Also, find links below to press accounts of OMC activities related to the protecting and preserving Lewis Hollow site.
1) 2006 letter from NYS archeologist Beth Wellman (deceased) attesting to Native American excavations in proximity to the Lewis Hollow site.




2) 2007 letter from Sherry White, (THPO for the Stockbridge-Munsee Band of Mohican Indians, at that time), to NYS SHPO, regarding the stone mounds in Lewis Hollow. LINK

4) 2009 NYS Museum archaeologist and GIS specialist Susan Winchell Sweeney’s GPS/GIS feature location survey map of the stone mounds, walls and springs identified at the Lewis Hollow site.

10) 2021 Report from Dr. James Feathers of the University of Washington, providing results of the  soil samples collected at the Lewis Hollow site, for analysis and dating, using Optically Stimulated Luminescence (OSL) methodology.  The results indicated a construction date of 1550 AD, for Great Cairn #4, at the Lewis Hollow site.

Peer reviewed paper published in the journal Quaternary Geochronology. “Luminescence dating of Enigmatic rock structures in New England, USA”, by Dr. James Feathers of the University of Washington. Includes dating of the Lewis Hollow site in Woodstock New York to 1550AD, making the dated features the oldest man-made stone constructions found in Ulster County. Additional OSL dating results for Lewis Hollow will be available later this fall.

OMC Chairperson Glenn Kreisberg has recently published a book about his 10 year quest to understand the lithic constructions found in the backwoods of the northeast, including the Lewis Hollow site on Overlook Mountain. When you purchase a copy of Spirits in Stone from the OMC website, you receive a 10% discount PLUS 10% of the proceeds are donated to Overlook Mountain Center.

My new book, Spirits in Stone, will be out April 10th, from Bear & Co. In it I document over a decade of research into man-made stone constructions in the backwoods of the northeast, with a focus on the Catskill and Shawangunk mountains of New York. I examine the potential origins and purposes for a myriad of different types of old stone structures found on the land, including walls, cairns, perched boulders, effigies and more. I also examine important sites around the world for insights into ancient megalithic culture. In the northeast U.S., as elsewhere, the patterns revealed through the eye of landscape archaeology and archaeoastronomy speak to the sophisticated belief system of an ancient population that understood the complex movements of the night sky and integrated those beliefs into their lives and world view. I believe they accomplished this through the cultural practice of celestial observation, landscape manipulation and monument construction, as well their travels and contacts with peoples from other regions and parts of the world. This is controversial information, as generally for our region, this is not accepted to be true by conventional historians. I hope this book helps change that view.
