Here is Scott Ramsay's description of the hole, taken from his "Courses by Country" piece:
"Ninthhole, 215 yards, Biarritz;
The author’s favorite inland one shotter, the view from the tee willstay with the golfer until his dying days. The feeling one gets playing the hole the first several times is that of standing on a precipice hitting over an abyss to a green that is impossibly far away. The reality is only slightly more on a human scale with tee perched high on an embankment sixty feet above Griest Pond. On the far side of the hundred yard wide pond is one of the world’s largest single putting surfaces, measuring sixty-five yards from front to back and including a five-foot gully (!)through its middle. The sheer audacity of this 12,000 square foot green sets the hole apart in world golf as, after all, no further dramatics were really required given the heroic nature of the tee ball. In theory, the player is to use the front slope of the gully to help sling the ball to the back hole locations. Thus,as with every full length Biarritz, it should be mandatory that the hole be placed on the back half of thegreen the vast majority of the time as the tee ball is more varied and interesting. Indeed, when the hole is forward, and given the downhill nature of the hole, the tee ball is often struck with little more than a mid-iron. This robs the hole a tad of the excitement that must have been present in the days of hickory golf clubs when a five wood or long iron was required."
