Dave,
Wolf Creek is a study in shaping, not "minimalist" architecture.
Wolf Creek was Rod's first solo design, after working a couple projects for Pete Dye. He hasn't moved even close to as much dirt since. In fact, Rod says every square inch of the property at Wolf Creek was touch, and re-touched by a bulldozer blade!
Funny, he's consistently complimented on his "great use of a great piece of property" at Wolf Creek. That's a testament to Rod's abilities as a golf course constructor who can create artificial features that look remarkably natural.
Blackhawk was totally different. Very little work was done there other than shaping tees, bunkers and greens. I can only think of two, maybe three fairways where any notable shaping work was carried out.
Although Rod would never use the term, Blackhawk is way more "minimalist" than Wolf Creek. Way more. In fact, the architecture at Blackhawk is very "minimalist".
