Olema is a small town in West Marin County, North of San Francisco. It straddles the San Andreas fault line. The West side sits on the Pacific tectonic plate and the East side the North American plate. In 1906 the San Andreas fault ruptured North and South a distance of 296 miles creating dramatic earth movement in Olema. The Skinner Ranch red barn still stands today along with a section of fence which was displaced 18 feet by the great quake. The fault line passes under the Southeast corner of the barn. When the fault snapped in 1906 the barn and it's foundation shifted Northwest 15 feet dragging the Southeast corner with it.
