Ted:
I'm not sure exactly which year Camargo was built. I thought it was earlier instead of right at the end of Raynor's career, but I used the 1925 date [actually 1926] in The Confidential Guide.
I can tell you that Yeamans Hall's greens were pretty flat [and buried under topdressing] when we redid them in the late 1990's ... we had the plan that Raynor had drawn, so we put back ridges where he had indicated on the plan. [Though I have no real evidence that they were ever built like that to begin with.]
As for Camargo, we have never touched the interior contours of the greens, nor did we do them all at once. They were expanded back to the edges, which involved raising some of the edges, and most of that work was done in-house in the early 1990s. [The bunkers were done separately, later.]
It's entirely possible there was more contour in the original greens that was taken out of them at some point along the way: I was told that the superintendent at The Creek did the same thing back in the 1940s and 1950s, for example. Indeed, I would expect the greens had more contour to start with. But I've never been tasked with restoring that contour, and it would be hard to do unless they decided to rebuild them all, because it would be so difficult to match the soil profile of what exists now.
