Sweetwater Marsh NWR, Imperial Beach, California: This bit of salt-marsh habitat, just 315 acres, is all that's left of the huge salt marshes surrounding San Diego Bay. The refuge was developed as a result of a court-ordered settlement over a development. Image digitized from original slide WV-10858-Refuge Centennial.
