A couple of items.
Lynn I stand corrected on the routing from our discussion on the other site. Although Fazio and from what I understand Tom Doak did routings on this property, this routing is from Bill Coore.
As far as the length, I played with a guy who is a solid 1 handicap and we played from the blue tees and it was solid and yet fun. Bill Coore doesn't care about Tiger Woods or pros and anybody playing the Black tees is going to have a real test and yet have fun. The ratings are,
Black 72.6 / 140
Blue 70.7 / 135
The course is a par 70. You don't hit driver on every hole, the 3rd hole is an example. That hole is the #3 handicap hole and plays 508 from the Black and 466 from the Blue tee. As Ben Crenshaw says, there are some "stout" par 4's there. I do agree that the 3 par 5's are reachable, but the 13th is 589 and the green is severe and you really need to position the ball correctly. I also agree that the elevation, around 5000 feet didn't effect the ball as much I thought.
As for Lynns "safe" statement, what C&C course isn't safe? I don't consider either Sand Hills or Friars Head to be penal in the Pete Dye sense. There are a number of holes at Clear Creek that if you miss it or hit it in the wrong spot you are going to be in deep trouble.
There are spots that also help you. The below photo as IMHO one of the best greens on the course. Although you can't see it in the photo, there is a large swale in the middle of the green. As a result, when you hit you shot onto the green from this location, the ball disappears and you have no idea how it ended up. On the flip side, if you hit the ball to the right of the green its unplayable. In terms of a little soft, if you the ball to the left, way left, the ball still will bounce down onto the green.
