Rock patterns, Moonstone Beach, Cambria
These are late Cretaceous greywacke sandstones of the Cambria slab. They are interpreted as submarine landslides into a large marine canyon, something like the present-day Monterey Canyon. Ordinarily they look like massive, grey, featureless sandstone. But in flat light & when they are wet, sometimes you get enigmatic hints like this. . .
Field of view is about 2 ft (60 cm) across, by memory.
