Not a punchbowl, more like a saucer. And no, not inverted.
The 10th green at Holston Hills is my favorite architectural feature on the golf course. While the hole is flat, Ross sited the green on a slight upslope that also falls slightly from right to left. Rather than construct the green at elevation, however, he dropped it slightly across the entire front, perhaps no more than 18 inches and cut it into the bank at the rear, perhaps two to three feet. The right side is also cut into the hill while the left is slightly above grade to facilitate drainage. The result is a right to left sloping green and a sort of truncated punchbowl where the bottom of the flag is always hidden.
A great example of a hole that is timeless. I'm guessing at one time the player approaching with a long iron looked on expectantly as his ball bounded once or twice in front of the green then disappeared onto putting surface. Similarly, today's strong player approaching with a short iron cannot confidently judge distance to yield a reasonable birdie opportunity, particularly with the green's cant.
I'd be grateful if someone could post a photograph.
