Hog's Back Hole :
A favorite of Seth Raynor and Charles Banks was 'Hog's-Back,' which can refer to the fairway, the green or both. The tee-ball to a hog-backed fairway is like playing to a Donald Ross green - very uncomfortable and a bit intimidating. When it refers to the putting surface, there is usually a sharp spine running through the length of the green, back to front. From the center of the fairway the golfer is faced with the problem of producing an accurate enough approach to find the correct segment of the green. The spine will dramatically deflect balls left or right.
The area to the sides of the h/b are easily 15 to 20 feet wide - again they are not linear - in some areas to the right of the peak of the ridge it may be 8' and on the other side of the peak it may be 14 feet - so you have totally different slopes throughout creating some of the most interesting putts you can imagine.
The ridge should be sort of down the centerline of play - or just a bit across it - not at right angles to play. I guess the average height thru the ridge would range from about 1' to about 2.'
Sometimes, the Hog's Back refers to both a fairway and green combination, this leads to all sorts of problems for an approach shot.
