The 2026 Greater Mysteries fall cycle begins with an evening of exploration, inquiry, and conversation.

Archaeoastronomer, author, and researcher Glenn Kreisberg invites us into the remarkable world of Hudson Valley’s ancient sacred sites and the sophisticated cosmologies that shaped them. Drawing on decades of research, Glenn reveals how Ceremonial Stone Landscapes (CSL) were aligned with the movements of the sun, moon, and stars, creating places that were consciously attuned to the rhythms of the living cosmos.

Rather than viewing these sites as relics of the distant past, this presentation invites us to consider what they still have to teach us today about relationship, ritual, and our place within a larger universe.

Following Glenn's presentation, he will be joined by Theresa Widmann for a moderated conversation exploring the relevance of these ancient traditions for contemporary life, followed by an opportunity for audience questions and discussion.

Whether you are new to mythology and sacred traditions or have spent years exploring these subjects, this evening offers an inspiring doorway into the themes that will unfold throughout the Greater Mysteries fall series.

This event serves as the opening gathering of the Greater Mysteries fall cycle and offers meaningful context for those planning to attend the culminating cave experiences at Widow Jane Mine.
