Knoll Hole :
The 'Knoll' hole was first built at Piping Rock's 13th hole. The original is the 4th hole at Scotscraig GC near St. Andrews. I wrote to Scotscraig and sent them a photo of the 13th Piping Rock - they were amazed at the similarities. The design is presented as a short par-4 between 310 and 340 yards. At its best, the Knoll genre is played to an elevated green - a much higher version of the 'Short's' plateau. If original, the putting surface should include a single plateau covering the back third of the putting surface. The green was usually only moderately bunkered if at all. Do not go over the back - at Piping Rock - the drop-off is near 20-feet.

There is an interesting version at Yale's 376 yard 14th, where the tee-ball can be banked off hills to the left but the green is quite moderate (no bunkering originally). It makes a wonderful drive and pitch hole.
