Ned,There is a new book coming out this fall on the history of Pebble Beach Golf Links, with quite a bit about the evolution of the course. It should be an excellent book, and hopefully will clarify your question, because I wonder the same thing about #8. Robert Trent Jones has claimed credit for one of those bunkers, which means nothing of course. More likely, it was Egan or a course superintendent over the years.MacKenzie rebuilt eight and thirteen greens in 1926, presumably as an audition for the big redo in 1928 that was eventually awarded to Chandler Egan. Neal Hoteling, the Pebble Beach historian who has put the book together, says that Egan tinkered with MacKenzie's eighth green during his 1928 work, but I don't recall him mentioning the addition of bunkers. Just work to the green edges and front contour.I can tell you that the left slope you are talking about was an original course design feature. It was a nasty, geometric bunker that MacKenzie filled, but evidently decided to leave for the purpose you suggested - working shots off of it. But who made it sand again is a good question, and it could in fact be his Trentness.Neal's book also promises to reveal who made eighteen into a par-5 in the early twenties. It was not Egan, and it's actually somewhat of a surprise. But I've been sworn to secrecy until the book comes out.Geoff
