The above photograph of part of Stark's Knob near Schuylerville, New York, shows an old pillow basalt quarry face. Pillow basalts are created when magma erupts under water. Stark's Knob formed about 460 to 440 million years ago (Ordovician Age) in relatively shallow sea water. This modest mount played an important role in the Battle of Saratoga during the Revolutionary War in 1777.
