Below is an overhead of the 338 yd slighly dogleg short par-4 10th hole at Bristol & Clifton. A thoroughly nice, traditional, well groomed UK parkland course/club, not overly infested with trees, in lovely surroundings on pretty free draining land. A course well worth playing IMO.
Anyway, to get to my point.
The 10th hole has a small, low mound, probably not much more than 2 ft high, positioned about 5 yds short of the green. It's a tiny feature really, pretty inconsequential at first glance and difficult to even see from the centre of the fairway, but it seems to have a big effect on the play of the hole.
Land short and try to roll the ball onto the green - the green incidentally falls away from front-to-rear quite significantly - and the ball will stop short or roll off to either side leaving awkward next shots. Land on the far edge of the mound and the ball will whizz to the back of the green or maybe even beyond.
As you will see from the photo below, which is from the clubs fine website, the small mound is so low as to be vertually invisible from the centre of the fairway.
So my quesion is, on what other courses does a
single small, low mound have a significant effect on the play of a particular hole?
