I have a vauge idea what an 'ALps but what is the definition and whats the origional?
From the interview with George Bahto on Gca.com
Alps' was a term describing a blind shot throughout the British Isles - the original was the 17th at Prestwick. The 3rd at National is an awe-inspiring version. A 'mountain' must be carried on the approach shot to a green fronted by a deep cross bunker. National's Alps is considered an anachronism to some, but students of the classics consider it a wonderful tribute to days gone by. It was the end of the era of blind shots, but C.B could not resist when he found a natural Alps site when building his Ideal Golf Course. Seth Raynor built an Alps on most courses, but they were generally identified as having 'Alps bunkering' - meaning some cross-bunkering in front of the green. Instead of a blind approach over a 'mountain,' Raynor customarily positioned his Alps renditions just over the crest of a rising fairway - then cross-bunkering the green complex. Sadly, many clubs covered in the cross bunker because they did not understand the origin and concept. Alps greens usually had a spine of sorts running through the green to compound putting problems.
I also recommend that you check out his excellent book "The Evangelist of Golf" which contains in depth analysis of all the so-called template holes.
Cheers,
