PRESQUE ISLE STATE PARK  42.14N, 80.10W

"Lake Erie is one of the Great Lakes, and part of the world's largest supply of fresh water. The sample os taken from Short Jetty Beach, one of the Mill Road beaches, on Presque Isle State Park. The photos I did get show the breakwalls which have been built along the shore to limit erosion.  You might notice the scalloped appearance of the shoreline due to the breakwalls.  Presque Isle is a peninsula in Lake Erie and actually shifts positions over time.  The sand that erodes from the shoreline is deposited at the tip of the peninsula which in turn lengthens the peninsula over time.  Using Google Earth and looking at views of the peninsula over time you can actually see the shifts in the shape of the peninsula."
