"Astronomical Alignments of Hudson Valley Stone Sites"
There are hundreds of stone chambers, walls, and perched boulders in the Hudson Valley that have astronomical alignments. Are they colonial, Native American, or of some other pre-Columbian origins? The talk will be given by Linda Zimmermann, an amateur astronomer and former chemist turned author of over 30 books.
As usual, the lecture will be at Lienhard Lecture Hall at Pace University in Pleasantville.
