I actually don't think Pebble Beach is recognizable at all. It's sort of a nondescript tree. Shinnecock is more recognizable than Pebble I think, if for no reason more than indian mascots and logos are becoming rarer. From a personal standpoint, before someone added a picture of Pebble's logo, I don't think I would have been able to remember what it was and I consider myself a pretty well-rounded golfer. That's just my opinion though, of course.
