Adam,
Wasn't that a hit movie with Helen Hunt and Mel Gibson - "What minimalists want?" I guess until I get hit by lightning and hear their innermost thoughts, I should stay away from speaking for them.
For as much as many diss mounds here, its actually an interesting theoretical topic. Both Nugent (Harborside) and myself come out of U of I. Hideo Saskaki was there (I think with Nugent) and was famous in Land Arch circles for saying "The Land is Putty." Certainly some of that has filtered through to Dick, maybe Tim and myself. There were other influences to the mounding era as well - both golf specific (spectator mounds, Scottish/Irish recreation desires, containment, shadow creation) and (I think) the desire to simply explore the outer limits of earthmoving capabilities.
Chambers Bay is mounded everywhere, but well done. Early examples like JN heap mounds have recieved less acclaim. Many of my own mounds got built too artificially. There are some theories as to how to avoid that, which I ignored early (the land, was after all, putty!) somewhat thinking that if I was going to move earth, I wanted people to know it. In other words, the visual composition could include scale, wow factor, etc.
Too much to post, but there were reasons so many gca's built so many mounds. And that they were built is reason enough for so many gca's to look for a new look.
