Every now and then I come across a wall or a garden boulder that’s so beautiful I have to take a picture. Such was the case with this serpentinite specimen on or around Huntington Street.
This is near Oakland’s great serpentine patch, and it likely came from there.

Yes, that’s a fantastic locality, much more extensive than what we have. But all the features you can observe over there are present in our serpentinite too.

I know it’s not in Oakland, but there’s some good outcroppings of serpentine along Highway 35 and Cañada Road along Crystal Springs reservoir.
