An old routing of Palmetto Golf Club dated April 12, 1931 shows all the green sites as presently located the best I can tell.
This plan predates Mackenzie's first visit to ANGC property on July 14, 1931.
The most significant tee change since 1931 routing was the 7th tee. The original tee was to the right of #6 green, making for a short uphill par 3 of 110 yards.
The change in tee location at the 7th significantly cut down on the hole-in-ones. Previously, as the story goes, the caddies went ahead, up to the 20 foot elevated green, and apparently a hole in one was not especially unusual. Probably made for a better tip
