Mike,
The search engine for the archives on this site is like the 18th at High Pointe, it doesn't fit in with the excellence of the rest of it so I shouldn't have given you a hard time about that.
I think your efforts to learn more about architecture are admirable; that is the same reason I frequent the site. I am a little surprised that you haven't at least seen pictures of heathland courses. I mean hell, the Women's British Open was just held at Sunningdale (Old) and was televised. For a good description of some of the better known heathland courses, you can start with Darwin's "Golf Courses of the British Isles." From there, you can get Tom Doak's take on them from picking up the "Confidential Guide". He has some pics in there, but any big bookstore (or maybe even a small one in Pinehurst) will have a coffee table book with Wentworth, Sunningdale and Walton Heath in it. Take a look at Geoff Shackleford's "Golden Age of Golf Design", pages 21-24, for a peak at St. George's Hill and Sunningdale Old. The holes are completely framed by pines now, but at least you can get a sense of what the holes looked like when they were first laid out.
To compare Heathland courses to Pinehurst No. 2 is pretty rough stuff. No. 2 is one of my favorite courses in the world and, in my opinion, most courses will not fair too well against it; but the thing about Surrey isn't so much that it contains world beaters like No. 2, but it has incredible depth of quality. Talk about a tough neighborhood.
I come from Southern California where there are architects with very successful practices who don't play golf and by their own admission (in interviews I've read at least), they've said they don't even like golf. Not surprisingly, they create some really good landscape architecture, but as interesting golf courses their creations fail miserably. If I treated you unfairly, I apologize, but it struck me as odd that you are teaching a class, but haven't been able to get a sense of what a Heathland course looks like.
If your aim for your class is to give future supers and potential architects some understanding of the principals of design, I would recommend Doak's "Anatomy of a Golf Course" for the textbook. After all, the concepts of strategic design are the same from course to course. Heathland golf is different from parkland golf in its hazards and potential (firmness of the ground with being hardpan), but, again, without getting your student to understand the concept of a Redan hole, looking at pictures of Redans from around the world will likely not be as beneficial.
I have some decent photos of heathland courses, but unfortunately no scanner. If you would like to discuss them more I would be happy to. I can also dig out my former posts on some of the heathland courses I've played and email to you. If you are interested email me at jreilly31@btinternet.com
