The old railroad followed the edge of Discovery Bay, cutting across the salt marsh at the head of the inlet and isolating some small estuarine lagoons (maybe just one, originally) along the southwestern side of the bay. The old mill (Maynard's, I guess) sat along the railroad, perched on what was probably the original spit. A mill pond was created behind the mill at one end of the lagoon.
The mill had pretty much dismantled itself, but the remnants remained until NOSC (see below) went to work this fall and removed the old structures and much of the old fill. They dropped the elevations to more closely match the geometry of the old spits and they replumbed the small stream mouth and the estuaries.
This is a fairly sheltered site since it's tough to generate big waves in this corner of Discovery Bay, but there will still be enough energy to gradually rearrange the beach. But the bigger story will probably be the riparian vegetation and the fringing marsh.
Walking the beach last Tuesday, there were a few pieces of the old timber structures, and the shape of the shoreline still mimics some of the historic fill, but in a few years, the human history will be almost entirely erased. (The photos were all taken the same day - the foggy one in the morning, the others on the way home).
