Tom and Ed are both spot on with their assessments of the missing space. In the 4th image, you can see the drop peeking over the rise in the rough, just shy of the front, right bunker. That bunker sits below the surface a good bit, I recall. If memory serves a wee cup more, the green has a lower front-right and a higher back, offering a good bit of segmentation. You wouldn't go after a back-right hole location, given the sand and the drop off.
In the overhead shot, all the brown grass to the right is precisely where the drop off lies.
It's an interesting thing with specimen trees. Sometimes a membership just won't give them up. It happened on #17 during the restoration of CCBuffalo, preventing a true return of the fairway to its Ross origins. I suspect that trees like this one on #2 at Teugega are less than 90 years old, so they weren't part of the original plan.
