Plymouth, Massachusetts

"Chase the Shades of Night Away":  You should be worried. Here's a lighthouse too close to the edge of an eroding bluff. This landform, which was created by glacial deposition, will soon succumb to the forces of erosion originating with wave action, especially that which accompanies high tides during storms. Soon, wave-cut notches will undermine the exposed edge of the moraine, gravity will take over, and downslope movement will result. At some point, the lighthouse itself will become a victim of the mass wasting, and its skeletal remains will ultimately become part of Neptune's domain. Enough physical geography for you? Or would you like to add rising sea level to the prognosis? Vine Hill Cemetery. [2008]
