Visiting Dracena Park in Piedmont, California, U.S.A.

This park used to be a quarry for a low grade of sandstone. Here's some more information about the geology of the park from the Oakland Geology blog:

Now it has been repurposed as a park, with a lawn and a children's playground, which you can see in the distance.
A pleasant place to spend a summer afternoon!
