OK, some accuracies and inaccuracies to clean up here.
Bryan Izatt: Yes, as your pictures depict, the first and second holes of the Red course were torn up thirty feet deep by mining operations in early 2010, and then put back together by Bill Coore's team (with a lot of fill from elsewhere on site) after the fact. In your second to last picture, just left of dead center, you can actually see the huge drag line machine that did the mining -- the site had been cleared but it hadn't started digging yet. This was the same machine that did most of the earthwork on site 30 years ago -- a machine with a 300-foot-long boom, a bucket that could easily scoop a pickup truck, and a cab the size of a small house. That's how those 90-foot dunes that Pat loves so much on my seventh hole got stacked up so high.
Joel S: I don't know who told you what about the earthmoving on the Blue course, but what you said is quite wrong. The 12th hole on the Blue course WAS filled [with sand from the 13th fairway], but it wasn't a lake, and was only filled an average of 3-4 feet. That probably amounts to 25,000 cubic yards of earthmoving from 13 to 12, and that was the biggest piece of earthmoving we did. [Ironically, we moved similar amounts to sand-cap the 4th, 12th, and 13th holes at Pacific Dunes.]
Our other biggest piece of earthmoving was extending the Blue 14th fairway out into the lake a little bit, with some dirt from the left side of #15 and from the slope down to the lake. We'd planned on filling it out farther, until we pumped the lake down and saw how deep it was. That's why Adam noticed so much drainage work on #14 fairway ... if it started eroding into the lake, it would be gone pretty quickly!
The fairway that was completely filled from an existing lake is #5 on the Red course.
For Patrick: While I was very happy to get to build the Blue course, Bill Coore made the decision of which to take. He might have been doing me a favor, or he might have been trying to get "weight" on your scale for taking the site that required more earthwork [but I doubt it
]. He says he took that one so that his crew would have a few more months' work, which they did. Whatever the reason, I didn't "grab" the better site from him.
Lastly, Michael George: As a golfer, I don't know why you'd care where we moved dirt. If you're interested in architecture, though, you might be interested to know the details of how it really happened.
