Many people haven't seen what the entrance to Bodega Harbor looked like before the North and South jetties were built in 1942. Note that the tip of Doran Beach was recurved inward towards the inner portion of the harbor (on the inside of Campbell Cove) — creating a very narrow entrance to Bodega Harbor (sometimes referred to as Bodega Lagoon at that time). It now curves outward, but the current shape is artificial and is dependent on the jetties and bulkhead (on the inside of the spit).
This U.S. Army Corps image also shows the natural shoreline before Westshore Road was constructed and before PG&E began development of the site for a nuclear power plant (never completed) at Campbell Cove.
It also illustrates Gaffney Point (the sandy point at the top of the image) in a nascent stage without much vegetation (dune or salt marsh)...and the Gaffney Ranch site just to the right of Gaffney Point.
Thanks, Janet, for inspiring me to share this historical image!
