Potsdam Sandstone Festival

On Saturday September 21st, Jeff Chiarenzelli led a walking tour of the Red Sandstone Trail in Hannawa Falls in conjunction with the Potsdam Sandstone Festival.  The Red Sandstone Trail follows the west bank of the Raquette River past the site of former quarrying activities including the Parmeter Quarry the first established in 1809.  Photograph shows sub millimeter-sized, highly rounded, detrital zircon grains separated from the Potsdam Sandstone.
