Colin,
Your question is impossible to answer. It's not the constructed features that stick out, to identify, but, it's artfulness lies in how everything ties in, or juxtaposes nature, in such a way that it evokes an almost visceral response, either consciously, or not. The subtle nature of the ravine, on the opener, can't be quantified, or can that little pimple on the green collar, over the hump, on the right front of #2 green. Or, how the course turns back up valley, intimately connecting the entire front nine. None of this will answer your question. Neither will the freedom nor strategic nature of the 11th and 12th. Or the uniqueness of 13. And then the climb to the high point after the par 3, and then it's climactic descent. None of those aspects will help you remember, how subtle the greens flowed, will they?
