Lost Landscapes and Hidden Legacies:
A Survey of Stone Structure Sites in the Hudson Valley, Shawangunk and Catskill Mountains of New York
with Glenn Kreisberg

Putnam County, NY.

Does evidence exist to support the theory that an ancient cultural group used features in the landscape of the northeast woods, to carry out astronomical observations?  Is there an explanation behind the preservations and alignments between the horizon, landscape features and manmade monuments? Some arrangements appear configured over great distances where petroforms and geo-glyphs have been discovered showing correlations to star constellations in the northern sky.  These findings hold the potential to reshape our understanding and concept of what ancient (prehistoric) man, in our region, knew and was capable of accomplishing.
