This is a more geographically general post than most, since my goal was simply to capture several shots taken as we traveled between the Cape Rondeau area and the western end of the lake. This shoreline consists mainly of bluffs, many of clay or silt, but there are also low beaches, including the large barriers that have formed at Point aux Pins and Point Pelee.
The geography of this shoreline appears to be controlled by larger glacial features and sediment variability, subsequently reshaped by Holocene coastal processes. Humans have left their mark, too, with jetties, lots of groins, and a mish mash of armoring, at least locally. Most of the shoreline development is on the low beaches, probably because the bluffs are eroding quickly enough to discourage building and because the demand for Lake Erie view property isn't the same as on Puget Sound.
The timber groins are at Erie Beach?, just west of Erieau (Aerial).
The bluffs are at Point Alma (Aerial).
The sheetpile groins are on the west side of Point Pelee, near Seacliffe. (Aerial)




A long drive across North America ended today with two beaches on its far right edge. The coast of Maine, at least of southern Maine, has a rocky framework with beaches filling in the interstices. In some places, like Ogunquit and Old Orchard, the beaches are long strands and dominate the landscape, while on the midcoast, like at Reid and Popham, the rocky skeleton stands out and the beaches are small and isolated.
Our first view of the Atlantic was through an Independence Day weekend crowd of kites and balloons and sunbathers. The east end of Beach Street crosses to the southern tip of the spit and people covered the sand on both the ocean side and along the river on the inside. Farther south, across the small river, are the rocky headlands that extend south toward Cape Neddick.
The waves were gentle and the beach was flat, with a broad low trough (runnel?) separating the upper beach from an equally subdued bar at the water's edge.




Spuyten Duyvil (remember, New York was settled by the Dutch) refers to the area at the west end of the Harlem River, where it converges with (or diverges from) the Hudson. The original channel looped around, but was later straightened with dynamite, shifting neighborhoods back and forth between Manhattan and the Bronx, sort of the way the meandering early Mississippi brokered land swaps between Mississippi and Arkansas.
The beach with the forest rising behind it is pretty remarkable. It is in Manhattan, albeit a remote corner of Manhattan, tucked in behind the railroad bridge at the north end of Inwood Hill Park. I suppose technically it isn't really a beach as much as it is a sand bar, since there can't be all that much wave action within the river here. If there had been some sort of spit at the mouth of Spuyten Duyvil before the railroad was built, this could be the remnant of something long lost beneath the tracks, but that's pure speculation. Whatever the case, I thought the idea of an isolated beach in the forests of Manhattan was neat.



Before the trip, I had been reading Phillip Lopate's Waterfront: A Walk around Manhattan, a wonderful essay on history, urban planning, environment, and New York City, and a great introduction to the waterfront of Manhattan. Unfortunately, three days with a family in toe and a poor practical knowledge of the city's geography meant that my shoreline exploration was largely limited to what you could see from a Circle Line Tour around Manhattan.
But even that was fascinating. I could picture the Hudson River side, having grown up with pictures of Cunard liners on the walls at home, but I had no idea what to expect of the Harlem River or even the East River bridges. More of my personal observations can be found across the way at hshipman, but I will include here a few shorelines, less for their geologic insight and more as an introduction to New York City and an exciting urban waterfront.
Brooklyn, for the geographically naive, is on Long Island, and is separated from Manhattan by the East River, a tidal strait connecting New York Harbor with Long Island Sound. Its industrial shoreline is gradually giving way to high end residential development and a restored waterfront - the wharves turning into parks and promenades and even a pocket beach (created or an accident?) under the Manhattan Bridge.
