I have played 3 courses that I know to be designed by Alison, and all three are excellent.
Kirtland CC, north of Cleveland, continues to grow in notoriety, deservedly so. While living in Ohio, I was fortunate to play Kirtland on a few occasions, and really enjoyed just about every hole.
Orchard Lake CC, outside of Detroit, is spectacular. Despite getting some recognition lately, I think it continues to be one of the most underrated courses in the US.
CC of Detroit is pretty remarkable, as well. It is on a pancake flat property (save the 9th and 10th, which go up and down a small hill), and has excellent bunkering and greens. Awfully nice neighborhood around it also.
I’ve heard that Alison is best known in Japan, where he built several of the country’s best courses. He also presumably had some influence on several of the courses in England that were built while he was working for Colt.
I’m eager to see more of his work. Is there a good source for a comprehensive list of his courses?
