Faultlines - Mt. Tamalpais, Marin County, California
The San Andreas fault heads north from San Francisco, 12 miles to the south and continues on in front of the Bolinas Ridge in the distance. It moved 16 feet in 1906. As if moves, it distorts the land around it, piling up ridges on either side. Erosion has enhanced the ridges in to the rounded sharpes that you see here. A dramatic misty sunset enhanced the look of these formations even more. You can see low fog over the Pacific Ocean in the distance on the left side. Above the moist redwood forest, the currently green grassland dries out in the 7-month summer dry season.
