"The bottom line is that, in terms of routing, the course is as Colt drew in 1913 for 85-90% of the course. No matter how long it took Crump to complete the job."
Paul:
I really don't know if you're blind, just don't know that course very well or you're such a Harry Colt advocate you just can't bring yourself to face facts.
For starters the routing of #1-4---and in my opinion, #6 (although numbered #8), #7, #17 (although moved to the right slightly) and #18 are Crump before Colt first arrived in Pine Valley. Most every one of them was described while clearing by Tillinghast before Colt arrived and that's the way they are today.
I sure wouldn't call that 85-90% of the routing Colt drew.
Then you have to add to that number #13, #14 that certainly aren't Colt. The way Colt drew #12 is about a 400 yard straight away hole with a drive right over the ridge. That's not what it is today and the 15th tee he has on the other side of the lake.
Crump's #15th hole on that stick routing in the super's office was from a tee in about the middle of the present hole to a green that appears to be almost exactly where #11 green is today. His #16 goes from a tee to the right side of that green to a green site about where #16 green is now but that hole on the original stick routing was a very long par 5!! Crump's #11, 12, 13 and 14 on that stick routing are nothing like they are now, although his original 10th isn't far off of what #12 is now---at least the tee appears in the same place. #13, #14 are the ones developed well after Colt left.
The holes that really appear to be undeniably Colt in the sense of being very different from anything Crump came up on that stick routing either in basic direction or use of landform (tee or green placement) are #5, #8, #9, #10, #11.
