Lake Erie

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)
