Brent Hutto,
In some instances the slope is very subtle, almost imperceptable, yet, it retains a highly effective function.
In some cases the upslope may be at the foot of a downslope, which really deceives the golfer, but, because the slight upslope is over a 3 to 10 foot distance, it's really difficult to detect from the area of approach or recovery.
# 2 at NGLA would be exhibit A.
In other uses, it's rather pronounced, like on the 12th hole at NGLA.
There, run up shots must impact the ground well short of the rise from the low point of the fronting fairway in order to be effective.
Balls hit 20 hards short, with the proper trajectory, will run up the slope, onto the green. Balls hit 5-10 yards short will stay on the slope or roll back to the low point. Balls hit to the front of the green, with a little backspin will also come back down the slope.
Now, the golfer is faced with a dicey shot.
Do they putt, chip, pitch or flop, and what are the consequences of a mis-hit shot.
# 7 and # 14 at NGLA present a slightly different slope, rising quickly from the fronting fairway. There, the rise may be about two feet.
But, the shot selection employed to deal with each of these features is different.
One must detect the feature, analyze how best to defeat or use it, and then have the courage to execute a shot not commonly used.
When employed in a variety of ways, the feature produces interesting architecture and golf.
