   Summary Author:  Thomas McGuire

   The  Helderberg Escarpment of New York State is located where
   sedimentary rock layers dip about 1° to the south, but the land surface
   dips to the north. This has created a broad, shallow  cuesta that
   ends at a steep north-facing slope more than 200 meters (700 ft) high.
   See diagram.

   Small north-flowing streams  fall off the  Manlius-Coymans
   Limestone edge of the  Allegheny Plateau at  John Boyd Thatcher
   State Park, 15 miles (24 km) southwest of Albany, New York. Rock
   formations are often named for the rock type (here, it’s
    limestone), and the geographic location where the rock unit is
   characteristically exposed. A walking path leads beneath both
   waterfalls. In the winter, icicles formed from the spray of the
    falls drape over the abrupt cliff. Photo taken on June 24, 2021.

   Photo details: SONY DSC-HX80 camera; 4.1mm; f3.5; 1/320 second
   exposure.
