Of course these bunkers "fit the land"
First, they are put into the natural sidehill coutours of the holes, not built up or otherwise made flatter, deeper, etc. Thus they "fit" the contour.
Second, they shape the holes, on terrain that does not seem to have much natural shaping features at least in the photos shown.
Third, they are clearly designed to keep balls from rolling off the course, or from hole to hole, after a bad shot. (Most golfers playing most courses hit mostly bad shots.)
Fourth, they even fit the sky. Aside from spectacular mountains, none of which are evident at this course, the sky is the most lovely aspect of the western landscape. Take another look and see how many of the bunker groupings mirror cloud patterns in the sky. It's pretty cool, actually.
You may not like the overall look of the place, but it isn't because bunkers don't "fit the land."
