Not sure how generous you are with your "Top Tier" courses definition but Sutton Bay has been the top rated course in SD basically since its inception.
Unfortunately after several successful and well received years, well over half of the holes of the original 18 holes began to sluff off the hillsides next to Lake Oahe (Missouri River) that they occupied. I believe the lake level was lower when the course was designed and "experts" thought it would never return to it levels from many many years ago, but after several wet years it did. That somehow changed the hydrodynamics in the soil structure and things started to slide slowly towards the lake. As I understand it at first they tried stopgap measures changing some holes, etc. But eventually when more and more holes showed the same signs they eventually built what in essence was a whole new course up on top of the bluffs abandoning the lake side holes. Views of the lake now, but no where near as close as the original routing.
Still listed as the top course in SD, and it is a good golf course, but not as good as when most of the holes occupied the land closer to the lake. If you look at sattelite images of the site now you can see some remnants of the old holes to the west of the current course wrapping around that point on the SW corner. Really surreal having played the original holes to play the new course and look down the hill to see the abandoned holes (albeit being reclaimed by native grasses). Some look like melting wax versions running down the hillside towards the lake.
Interestingly enough I just realized or remembered that the original routing is featured in our courses by country archive here:
