Reason for Designation: The advanced degree of pedogenesis observed in the albic argillisols of
Sidney Mountain Quarry and the oxisols reported at Skytop Lane Quarry in the study area have
not been reported elsewhere in NYS. The newly recognized paleosols in the Sonyea Group have
proven to be critical clues to understanding the dynamics of the Catskill shoreline. Sedimentary
features of statewide significance are recorded within the suite of tidally influenced facies at this location.
