Re: A Crooked House In Hollister

Hi Ladies. The creep rate apparently varies in an unpredictable way. Movement did not occur between 1910 and 1929, judging from the amount of offset in two sidewalks that were laid in 1910 and 1929, and in a pipeline laid in 1929.

Creep commenced sometime after 1929 and averaged 8 mm/yr. Between 1961 and 1967, the slip rate was about 15 mm/yr. Since 1979, two sites have been monitored in Hollister, one showing 6.6 mm/yr and the other, only 2.3 km northwest, creeps 12 mm/yr the fastest rate of movement measured across any fault in the San Francisco Bay Region.'' (For those not metrically inclined, 12 mm a year is half an inch a year.

The house is at the corner of Locust Street. Drive north on Locust until you have to turn left. As soon as you turn left stop. The house is on the left hand side of the street.

Creep along the fault isn’t level. In the area of Dunne Park there is a little ridge about 3 feet high. The fault is at the base of the ridge so the ground is being lifted as well as moving to the north in this area. There are other areas to the south of here where you can see the same thing. A drive on Union Road will give you good view of a ridge. You have to cross it.

A drive down Cienega Road to the Almaden Winery is always a good place to go. You can see evidence of both the Calaveras and the San Andreas fault. When you get to the Winery which is located on top of the San Andreas fault you can see where the Winery is being torn into. The owners of the Winery had to make a new door inside to let the fault move through. They haven’t decided yet what they are going to do about the outside wall. By the way the wine they make is pretty darn good. Take Care…Don in creepy town
