Plastic deformation at its ultimate! This outcrop of gneiss is visible along southbound Route 9 in eastern Connecticut. The S-curve of these layers is likely little noticed because cars zoom by at 65-70 mph. This foliated formation resulted from the deep compression of material that occurred during the shaping of the ancient landmass known as Pangaea, formed during the Mesozoic Era.
