I hope this thread does not go in the unintended direction of suggesting that any of the architects I mentioned are right or wrong or are doing things better or worse than anyone else. That was definitely not my intent.
Ed, I certainly didn't take it that way. I think you bring up a good point about the subtle or not so subtle differences in restorative work. Its important to understand that there was a wide range of people building these courses for Ross after he developed the drawings, some experienced in construction of a golf course and others not so much or none at all. Therefore, the finished product back in the 20's so to speak would have differences, soil types, grass types, construction budgets, owner mentality/intent, weather events, timing of construction are a few other variables that affected the final look and feel of the individual courses.
As far as greens go, if I have the original drawing and I can confirm the green was built to the drawing either through whats left on the ground, or through photos or some other record/memory available, I will restore that green as close to that plan as I can get. Because of changes in grasses, equipment, agronomic conditions and significantly faster green speeds today, I have to make adjustments at times to accommodate these things. I try to restore the golf that Ross envisioned not some museum piece that's not functionable.
#3 Green at Carolina is a great example of an original Ross green that remained prior to the project but one that had lost considerable surface area to encroachment along the sides and in the corners (@ 40%). The spine in the rear of the green and to either side of it were completely off the green and in the rough. It was clearly evident through ground features where the original green extended to, you could see the fill pad edge, however, I confirmed this by digging and probing the original construction to find the limits of the green. The current hole location in the back right corner of the green did not exist and was too steep 5-7% to leave it the way it was so I extended the green 2 feet wider to the back right of the spine and steepened the right side of the spine to soften the slope and provide a cupping area of 2 to 3 1/2 %. That little area was extremely tough back in the 20's with a green running 4 or 5 and I think you will agree it remains that way today. The rest of the green was excavated and restored based on what we were able to detect from the putting surface contours. Did Ross build those little subtle humps and bumps that I restored within the green, I cant confirm it in any way, there were not plans or photos to support it. Other than the fact the green had not be reconstructed I have to presume they were original. At the same time, I fully understand the effects of topdressing and maintenance on a green over 75 years so I take that into account when restoring the spines, swales, bumps or flashed edges etc.
David, I take not offense at what you say, I just don't see it and the greens at Sedgefield are vastly different than the other two courses you mention. Myers has more spines than the other two combined however most of them enter the green in the center back portion of the green splitting the back half. At Sedgefield there are two greens with spines entering the green from the sides or mid way back on holes #6 and #13. Actually, I would have like to seen more spines or ridges coming deeper into those greens, the punchbowl green on the 9th may of benefited from a bit more intrusion of a spine into the front center section. Most everything else are rolls and bulges along the edges or within the green itself. The two par 3's on the back were built from his plans and photos or from what remained in the ground, the 12th is a two tier green that curves because of the severe back slope behind the green and the 16th is a horse shoe green around a center front depression, resembles a toilet seat. Now if I can get the PGA Tour boys to stop putting the Sunday hole location in the bowl on 16 that little hole will come alive during the final round.
