Sean, Please don't let the bottom two pictures influence you other then what the features of both aerial look like. If you look and see what time I did the last part of the overlay, and which Mike Sweeney will attest at the time, the bottom two pictures didn't exist until I posted them later at almost 4:00 in the morning my time. The size of those two bottom pictures is not the the same I used in the overlay. I had sized the two for the overlay and then deleted the file, and then later felt it neccessary to add the two original pictures that were exactly sized.
The reference points I used were the lake where the small bay of the lake, the road from #2 green to #2 tee, the green itself, as well as the line of the two left bunkers. It doesn't always happen as such because of the different aspect of the two lenses taking the shots, as many times you get things to line-up in one spot and another side to be completely out of whack on another. This one didn't. It aligned to many reference points, including the what looked to be the original center of the trees running up the left. The only difference was that the trees have over-grown immensely to where they over-hang part of the fairway. Some of them may not even be the same trees, but the fact is that they were maintained and evolved as such.
Now as far as the green is concerned, I do think it's a bit of everything involved there. The green has moved and resided--probably even recovered in some areas and then the process evolved again. One thing is certain for me, I'm leaving it up to you guys to forge your own conclusions, because unless you get someone that is really adept at looking for compacted sand features of a bunker, the sand base of greens and knows the difference, especially on a sandy site (which Yale is not) the work is not going to be in align with it's original character, that much I know for sure, and I thank Kye Goalby and Sean McCormick formerly of the Valley Club and now Old Sandwich for allowing me to learn this. To think that the former superintendent who couldn't even get the right fairway mow-lines accurate, as a person adept at lookng for these features with a probe is about as laughable as saying that Peter Pulaski is a profound witness to them looking for them. On second thought, maybe it was Peter looking for these features and marking them out in line paint for construction. That would explain everything!
