Rows of Green Stones at the Harbor

I am not sure what natural and organic marine and geologic forces created these lines of stones covered with seaweed at the Point of Arches. But they sure look like they were designed with intention reaching out to the gorgeous sea stacks also reflected in the calm waters of a natural harbor. This image was taken close to sunrise at a very low tide on my recent backpacking trip to Shi Shi Beach.
