BLUESTONE WILD FOREST: A GLACIAL LANDSCAPE IN MINIATURE (MID-HUDSON VALLEY, NEW YORK STATE)
This glacial landscape sits atop Middle Devonian sandstones and shales of the Ashokan and Plattekill Formations on the broad Hoogeberg Plateau (122 to 190m msl) located at the base of the Eastern Catskill Escarpment. Large sandstone boulders scattered throughout BWF, as well as atop kettle depressions, provide evidence that the most recent glacier was mantled with supraglacial debris. Prior to the final down-wasting of stagnant glacier ice, at least one of the meltwater channels, the “Onteora Channel” may have served as an outlet for Saw Kill waters impounded behind the glacial ice that formerly occupied the lower Hudson Valley. This channel (~ 143m msl) is a nearly level, steep-walled, one km long gorge that is 50m above and 670m away from the nearest river capable of carving it. Other outstanding BWF geological features include knoll and kettle topography and a glacial landscape accented by a series of arcuate recessional moraine ridges riddled with chaotic jumbles of boulders marking temporary standstills along glacier fronts.
My research has documented an extensive glacial topography in the Catskill Mountain region. Furthermore, field research within BWF portrays an important early 19th and 20th century landscape that is eligible for the NYS and National Registers of Historic Places. Listing will recognize, preserve, and protect exemplary archaeological and geological resources.
