Next stop, Moonstone Beach, near Cambria, CA. Here we see shales,
sanstones, igneous clasts and others in the shales, surface burrows,
vertical burrows, load structures, soft sediment deformation, etc. We
interpret this sequence as marine fans, getting more proximal compared
to last stop, and some good examples of grain flows. The beach
derives it's name from the variety of colourful, well-rounded chert
pebbles found on the beach. They are eroding out of the chert layers
in the Franciscan; ancient marine siliceous sediment.
