Marin's Watery Environments

Marin County's San Francisco Bay Environments

• Wetlands Inventory (present land use)
• Marin

Based on the National Wetlands Inventory (F&WS, USDI) these images show farmed wetlands (orange), tidal wetlands (light green), and salt evaporators (red).
• Historic Bay Margins
• Marin

Historic open water (blue), historic marsh (light green), and present shoreline (black). In the north bay a comparison of this map to the Wetlands map allows you to see the wetland losses to salt evaporators (red) and farmed wetlands (tan).

• Changes in Marsh and Open Water Areas
• Focus on Marin
• Past and Present in the Ross Valley

These images isolate (non-farm related?) land uses in what were once historic open water or marshlands. The maps show the historic impacts of salt evaporators and land fill for urban development, airports and transportation related activities (i.e., Golden Gate Ferry Terminal in the Ross Valley

Just how does one get from a ferry boat going from Tiburon to San Francisco to the following dialog from Chapt. 2?

"And where am I?" I asked Johnson, whom I took, and rightly, to be one of the sailors. "What vessel is this, and where is she bound?"

"Off the Farallones, heading about sou'west," he answered, slowly and methodically, as though groping for his best English, and rigidly observing the order of my queries. "The schooner Ghost, bound seal-hunting to Japan."

And what does it say about the state of the tide when London produced "the accident"?
