Mount Tam, as it is known locally, is the center of Marin County. Not geographically, but being the highest peak of the Marin Hills, it is like a beacon leading us Marinites home from San Francisco.

The mountain is surrounded by national park areas offering up to forty miles of publically accessible open space. Mt. Tam was create by the uplifting, and folding of the North American plate as it slides along the Pacific plate near the San Andreas Fault. Does this mean we could one day loose our beacon?
