This is where Old Mill Brook passes underneath near the intersection of Norway Drive and Crooked Road. Old Mill Brook winds across the island, beginning at Thomas Bay. This is an area with old farmland and pasture, and of course, there was a mill on the brook long ago. There used to be a multitude of mill stones left on the island, you can see some of them displayed on lawns; others were sold off for big bucks, and still more may lay broken and grown over.
