(Station 1.) To the south, in the far left distance, is Mount Umunhum with its abandoned cold-war radar tower sticking up on the left. Behind it to its right, you can barely see the tip of L ...

Atop our vantage point, looking northeast towards Dad and the San Francisco bay, I'm surrounded by shoulder-high shrubbery.

Here it is up close. Pretty. Don't know what it is. Mom would know, but she's not along.

(Station 1 still.) Looking east from our viewpoint, there's a depression like a gully between us and the next hillside. That's where the fault runs.

(Station 2.) Looking mostly north, in the distance to the left (above the big V formed by the trees/shrubs) you can just see a couple of reservoirs in a depression between two ranges of hill ...

Some ferns along the path, fading for the winter. This is not the fault's fault.

(Station 3.) Much of the trail runs along a "bench", which is a wide flat area that looks completely like an old logging road that has grown over. As the earth pulls apart, sediment settles ...

(Station 4.) In the 1906 San Francisco quake, the two plates moved about 25 feet apart north of the Golden Gate. In this area, they moved only about 3-4 feet apart. This reconstructed/renova ...

And, off to the side, an old decaying wagon axle and wheel.

More of the same kind of moss I saw in abundance yesterday at Teague Hill.

(Station 6.) Here again, you can see the trail running along the fault bench. Posts all along the trail show the line of the actual fault or a subsidiary fault.

(Station 6.) The sag pond (here mostly dried up) is another sign of fault activity. The plates grinding against each other make very fine particles, a kind of clay, which forms an undergroun ...

Man, another fallen tree in our path, forcing us to go cross-country. Didn't I just do this yesterday?
