I think that the definition of "crowned greens" is an issue, as has been pointed out. I have always thought of them as "domed", "turtleback", upside-down bowls. I'm thinking of the first green at the Balsams--a 1915 design and a course that Ross was directly involved in. I've seen greens of similar design at Bethlehem, a course that Ross did in the 1910-12 period of time, and also at the Bretton Woods course--another 1915 course. On the other hand, the CC of Rochester, which I believe he did in 1910, does not have any greens that I would describe as "domed" o upside-down bowls. Courses I've seen, that were done much later, have no greens that I would define as crowned. Thus, my original conjecture about the evolution of Ross's concepts about the design of green surfaces.
