Like the geologic makeup of the Bay Area, the seafloor along the Marin County coastline is complex and often surprising. The Bolinas Museum History Collection was recently given several maps that depict the off-shore coastline of the Point Reyes National Seashore. These fascinating maps show seafloor characteristics from Bolinas to Tomales, created through multi-beam echosounder technology, taking millions of depth soundings from onboard a ship. Also on exhibit are maps that represent expected changes to our coastline as we experience sea level rise.
