I must admit I needed to reconsider my opinion for a few reasons.
There are great interior contours at Cataraqui and Highlands Links, but as I went through, I realized there were fewer good examples than I first thought. Btw, Cataraqui’s 4th green is the best interior contouring I have ever seen by Thompson. 3rd at Cape Breton Highlands would be my other top choice. To a smaller extent the subtle 6th at St. Thomas fits the bill too. I original thought of the 17th at St. George's, but that's a crown green.
If your defining interior contours as what Maxwell or Travis would have done, then he did not use interior contours. I think my comment was wrong on this. There’s just no body of work to make that statement. Some of the features I like and was including are actually crowns. The best one being the front right of the 15th at Jasper Park, but there are others on small layouts like Truro. In thinking this through, that’s not an interior contour. It’s often more of a false front. 6th green at Owen Sound (Legacy Ridge) is my favourite.
One of my biggest issues as I went to compile a list was how many courses I can’t use as examples. Here was my list of courses that have rebuilt all their greens: Banff Springs, St. George's, Cutten, Islington, Summit, Ashburn, Gavea, Sao Paulo, (and almost all) Sunningdale and Seigniory. So, I can’t use them, even though some greens only have minor changes. Then I have a second list of courses where lots of greens have been rebuilt: Burlington, Capilano, Galt, St. Thomas, Peterborough, Westmount and Oakdale (the original 18). There are original greens on each of those, but more rebuilds than you may think. There may be more courses, but I’ve not researched every history for green rebuilds. My ten-year dig was about original projects/renovations/false credit. I don’t include places like Waskesiu where my research says something different than the club. I’m going to stick with what I found and not include them.The best courses to see his original greens are Jasper Park and Cape Breton Highlands out of his very best-known work. Or the small nine-hole layouts that are often really intact like Allandale near Barrie. Some of the mining courses, but not all, many were done by Geoff Cornish.
My favourites are Allandale’s 1st (seen on this thread), Jasper Park’s 10th and Cape Breton Highlands 7th. The bucket pin on the 7th is insanely clever set in the middle of a tier. Peterborough’s tight cluster of 11th, 8th and 17th is fabulous. I do have pictures of all the original greens for Jasper Park, Banff Springs, St. George’s, Capilano and Cape Breton Highlands. There are some incredible lost surfaces like the original 14th at St. George’s was a roller coaster. So was the original 14th at Capilano.
Some lost greens that I was sad to see go include the 7th at St. George’s and Cutten Fields wild 14th which had a crazy clever lower tier in front behind the bunker. You can play that same green at the 4th at Oshawa G&CC. The best original green (my opinion) in Thompson’s repertoire may be the 2nd at Kawartha G&CC. It has a high tier in front and huge rise after on the right and a lower tier in the back left. It’s a one of one. So is the 2nd green at Cape Breton Highlands known at the top-hat green. That’s a wild set of contours too. He did do a lot of isolated tiers, that one happens to be higher than most and crowned. That was the great joy of the original 7th at St. George’s (the upper left crown).
I’ve gone to see a lot of his smaller courses and nine-holes and I do know they are definitely pitch green heavy. There’re some beauties at places like Dundas Valley, Huntsville and Owen Sound, but they are not what anyone would call great green contours. Same with the 8th at Oakdale (Thompson 9), but the long drawn of diagonal false front is among my favourite features because it leads the ball to the rear bunker.
So, I stand corrected, he did not do interior contouring enough to say that was a feature. If I were picking the source of almost all his movement, it would be best described as waves on the ocean. Often punctuated with a false front or tier when he was in the mood. But often it was just that rolling waves. On lesser work and early work, most greens are pitch greens with the variation of imperfection. And that's not interior contouring using Maxwell and others as what is.
I'll try post some lost green images if I get a chance.
