Spirits in Stone: The Secrets of Megalithic America with Glenn Kreisberg

A ground-breaking study of ceremonial stone landscapes in Northeast America and their relationship to other sites around the world 

• Features a comprehensive field guide to hundreds of megalithic stone structures in northeastern America, including cairns, perched boulders, and effigies 

• Details the Wall of Manitou, the Hammonasset Line, landscape astronomy along the Hudson River, and a several-acre area in Woodstock, NY, with large, carefully constructed lithic formations 

• Analyzes the archaeoastronomy, archaeoacoustics, and symbolism of these sites to reveal their relationships to other ceremonial stone sites across America and the world 

Presenting a comprehensive field guide to hundreds of lost, forgotten, and misidentified megalithic stone structures in northeastern America, Glenn Kreisberg documents many enigmatic formations still standing across the Catskill Mountain and Hudson Valley region, complete with functioning solstice and equinox alignments.
