Like RJ, I heard 6,000 CY was moved by scrapers or what not. I suspect some of it was the notch on 9FW that allows you to see some of the fw from the tee.
Many other greens and tees had dozers move small bits of earth around, balancing cut and fill on site.
I don't know why we are getting into the amount of earth moved at Sand Hills, but since I hit balls around it with Jim Urbina before they had done anything but mow down the prairie grasses, I've got a pretty good idea of what they did do.
The "earthmoving" they have always talked about consisted of taking out a rise in the 12th fairway that would have made a blind shot to the green. That's pretty much the only cut and fill that was done in a fairway.
A few of the bunkers were already there -- the big one off the first tee, the hollow left of #4 green, the blowout left of #7, in front of #15 green, and the bunker off #18 tee. The rest had to be cut out of the prairie grasses with a backhoe or excavator, any material from which was either lost in the fairways, or sometimes used as fill to build up the greens.
The day we hit balls around, I counted 14 greens that they could have just planted with the natural contours and called good; however, I think they did work to a couple of those, too. #2 green wasn't anything like what they built; #4 is all fill on the side of a natural slope, and #8 is on probably four feet of fill from all the bunkers in back of it ... that was just the low end of a valley to start with, and the one green site that I couldn't visualize what Bill and Ben were going to do.
In all, it took the least construction of any course I've ever seen; our own course at St. Andrews Beach is a close second. In both cases, no irrigation pond had to be built; usually the earthmoving from the pond is 5x as much as was done on these two courses combined.
