At my home course, Hotchkiss, Raynor used distinct arrays of ridges, segments and plateaux on 6 of the 9 holes. Most distinctive is the 3rd hole, an Alps with a nearly circular green. The green contains two spines perpendicular to the line of play, one running from 8 o'clock to 4 o'clock and the other from 11 o'clock to 2 o'clock. Even a short putt across one of them makes for a challenging 2-putt.
On the 2nd green, two ridges run diagonal to the line of play, offset by only about 2 paces. One runs from 5 o'clock to 11 o'clock and disappears into the green just past the middle. The other runs from 11 o'clock back to 5 o'clock, also disappearing just past the middle.
George Bahto calls the 6th green one of Raynor's best, and it features ridges like the three segment TV-dinner setup described above. The 8th green is also circular, with one quarter-sector raised 4-5 feet above the rest...
This is too much information, needing pictures or sketches, but the point is that the dramatic, even gimmicky, green features multiply the variety created by different pin placements. They also make approaches, pitches, chips, and putts of any length more fun and challenging.
