I am attaching a half dozen images of three large on private property in Brooklyn, CT, that I photographed on a hot April day in 2005. One (004 and 007) is beside a small stream. A hundred yards or so away is a huge platform mound (013), which measures more than forty feet along one side and is seven feet high (note the metric stick leaning against the well preserved side). Other shots of this mound (011, 012, 015) show that it has deteriorated significantly on the other sides. Perhaps stones were taken from it to construct nearby colonial walls. A third platform mound (022) is on the same stream as the first one (004), but it is pretty much gone except for the general outline.
