Michael, the last photo in your post is an old aerial that does not reflect the recent restoration of the hole to the original Colt design. As far as I know, it is the only other arrow-shaped green complex Colt created, other than the first one at St. George's Hill. Not sure exactly when Colt designed the green at St. George's Hill, but probably sometime in 1912, so the window of time when the design was on his mind is narrow. In early spring of 1913, Colt was at Old Elm and designed this second version. I wonder why he didn't use the idea more often because it led to such exciting tee and approach shots. Colt was not a believer in templates though, which might be the reason for its rarity. Colt's unique design was actually left on the drawing board at Old Elm because Donald Ross did not build it, but today it has been carefully retrieved. Not sure if the carry to reach the tip of the triangular landing area just over the bunker is 327 yards away. How did you measure it? The hole is downhill and it is downwind when the wind is coming from the north, like it often is in October. The zenith of Colt's design career may well have been in the years just before WW1 when golf architects were still artisans. His discoveries in the forests of Surrey in 1912 were brilliantly realized the following spring in North America with his two masterpieces, Old Elm and Pine Valley. Donald Ross was still an artisan too, and the green complexes at Old Elm might be some of the best he ever built.
