I think
@Kira may be interested in the following pictures that concern the San Andreas Fault.
The road to the parking lot above Mussel Rock in Daly City. The parking lot can be seen in the background and I marked the direction of the SA Fault in yellow. Notice how the road is buckling and cracking in this location. It looks different every time I go there because the ground shifts a couple of inches every so often. The fault is hundreds of feet to a mile wide and here I'm standing right on it on my telescopic legs.
You can make out the direction of the fault (diagonally in the picture) if you examine the cracks. Moneypenny looks grumpy.
Stepping over the guardrail next to may car, this is Mussel Rock just offshore. Right on top of the fault that heads out to sea and in a straight line to where the Pt Reyes Peninsula, I almost misspelled that, meets meets Bolinas and Tomales Bay. Again, I marked the rough path of the fault line, The darkish mountain you see in the background is the Marin side of the Bay where I reside. If you follow the curved shoreline for miles you end up at the Golden Gate and the entrance to SF Bay. This means the SA Fault runs just off the coast of San Francisco County. Very reassuring.
This is I-280 to the left and San Andreas lake to the right. The lake is a protected and heavily guarded reservoir and you can't leave the marked trails and go near it without security descending on you. It's all fenced in and secured with sensors and patrols, often guys disguised as bicyclists. The area has trails and bike paths. The lake is nearly 3 miles long. This is where Zorin's mine was supposed to be and where he wanted to set off the SA Fault. He also wanted to set off the Hayward Fault simaltaneously. He called his nefarious and insane plan Operation Main Strike.
This reservoir is a few miles south of SA Lake. It's also part of the fault.
I leave you with a picture of the scenery next to the lake. Like I said, it's a great area for running and biking.
