Minimalism in art is an old term, but it was first used in connection with golf architecture (as far as I know) by Ron Whitten, in an article for GOLF WORLD in 1994, I think. The two courses he focused on most were Sand Hills and the first course at Stonewall -- where, ironically, we moved something like 350,000 cubic yards of earth in construction. [What can I say? Tom Fazio did the original routing.] But Ron cited Kapalua and High Pointe as other examples of minimalism.
Everyone has their own definition of the term and most people's definitions are kind of free-floating, depending on where they want to stand about a certain course.
My own idea of minimalism (or at least, what I am really trying to do) is to rely on natural contours as much as possible, and to disturb as little of the site as possible. However, as I have pointed out here before, that doesn't necessarily mean you are moving as little earth as possible. At Tumble Creek we did more than 100,000 cubic yards of earthwork on a single hole (the par-5 4th) to blow through an impossible area, but by biting the bullet on those five acres, we came up with a routing that let us build the other eight holes on that nine without any earthmoving at all. To me, that is a LOT better than tweaking a little bit on every hole, because you only have to strip topsoil and hide your work on one hole instead of many.
I am wary of calling a project like The Rawls Course an example of minimalism. That site was dead flat and it was impossible to leave any significant portion of it undisturbed, because it had to drain somewhere. But when people tell me it's hypocritical of me to take a project like that, I have said that's not true, and point out how we designed it for efficiency in earthmoving and drainage, etc. So, I wouldn't label it minimalism ... I would call that naturalist, in the sense that we tried to make it look real even though it isn't.
In general, though, labels like these become meaningless once everyone starts using them to mean different things. "Minimalist" is now more of a buzzword, like "links-style" or "championship" before it. But I am happy to have helped promote the word -- even if it is now somewhat abused at least it's a step in the right direction.
