Adam,
Why Natural and Golf?
Because for Golf to work on all levels, nature has to play a part in it both deceptively and strategically to allow for the best, most exciting shots the game has to offer.
Many here will offer that Seth Raynor seemed to do pretty good for making things so geommetrical, or angled as Tom MacWood's latest offering describes. But what usually makes a good Raynor hole (at least from what I have seen of his work, and its a limited portfolio) is that he utilized the natural elements of the land and used them to make the shots work. Even with the unnaturally shaped features.
As time progressed, Raynor's work would have seemed to have taken a more natural look to it, as seen in pictures from Daniel Wexler's Lost Links and pictures he included of the Biarritz at the Cascades where the bunkering looked jagged and au naturale'.
You have to remember that for many years there was a lot of bad golf courses being constructed out there. These features looked totally out of place and eventually they were destroyed and rebuilt.
A prime example of this is Ananndale Country Club in Pasadena, California where the features looked more like manufactured pits, bumps and grinds, all of which were destroyed and eventually rebuilt into a really interesting golf course that utilized the terrain and the look of the existing area. Another was Virginia CC in Long Beach, California. Located on what is now the site of Long Beach's Recreation Park Golf Course, once existed a course much like Annandale.
Strategies for these courses were esentially non-existant, the shots to the holes were akin to a equestrian course with all sorts of blind hazards and hoorendous carries over clearly man-made objeects. It didn't work for golf, and it didn't work at courses like Annandale or Virginia either. Ironically, it was Willie Watson who built both of these courses, and eventually it was Willie Watson along with Billy Bell Sr. who would reshape and rework them into the great courses they would become. Only to suffer and devolve into the treed nightmares with loss and destroyed features that they are today.
A golf course doesn't have to have rough and ragged bunkers to look or play natural. It has to embrace the natural features in the routing, the placement of greens, tees and fairways, and especially, the use of natural surface drainage. This is where so many architects today make their errors--by recreating the site in an effort to make he drainage flow very differently then the natural flow of things. They move hundreds of thousands of cubes of dirt to do so, and when they do, the shaping is less then artistic. Containment mounds are introduced to both confine the holes and to rid themselves of potential liabilities. Concrete is introduced for cart paths and in some cases drainage channels--how unnatural and ugly is that! It eventually takes away from the scheme of the natural beauty of what a great golf site is all about.
Many will introduce The Lido as a prompt contradiction to what I speak of, but its all heresay. we get enamored withthe history and the uniqueness of the Lido, as well as the characters who designed and built it, but from the get-go, Lido suffered from countless problems as a golf course, both financially and physically. The sea even tried to reclaim her at one point. While the shots were most definitely there, and the extent of the construction impressive as well as its engineering--it was all far from perfect. It couldn't even over-come the financial burden it took to build it.
This is even when the natural ugliness of redevelopment took place!
