Sean, It is hard to tell but I suspect the farthest right side of green space that's visible is where the green slopes hard downward to the back half. That would make that other green area to the left part green and part approach. The amazing part is how invasive the ice plant has been since those many years, and, also how some other changes to the dunescape have occurred. I.e. the road that runs between the holes created a ridge that would likely make this photo impossible today.
Looking closer, I wouldn't discount Eric's guess. The shape of the either green would've been altered. The reason I was certain of it being the fifth, was the right side shelf. They must've added the back right bunker, cutting into the shelf and creating a slight back left bulb-like small shape. . How does one do a reverse image?
