The light beige are Holocene dune sand - geological epoch which began approximately 12,000 years ago. The dark brown are surface deposit of rocks, that occurred in Russian, Nob, Telegraph and other hills. The light brown are the parts of the Bay that were filled in the 1850’s. The medium brown was used to represent rocks that were crushed beyond recognition forming dune sand and lagoons and alluvial deposits. The darker blue represents the tidal waters that were filled.
