I'm becoming more and more curious how much of Whitemarsh Valley is really George Thomas, and how much of it was even George Thomas before Ross and Flynn respectively worked there in 1930 and 1934.
My strong sense is that most of what GT learned about golf course architecture he learned during the building of both courses at Merion, Pine Valley, Sunnybrook, Ross's changes at the original Philly Cricket, and Cobb's Creek, all of which came well after he did Whitemarsh Valley in 1908.
We know that Marion Golf Club in Massachusetts resembles a steeple-chase course more than anything natural, his 1910 design at Spring Lake got completely revamped by Tillinghast in 1918, and now Whitemarsh Valley seems to have been something short of strategically sophisticated when it was built by Thomas.
If someone has information to refute this understanding, I'd certainly like to hear it, but from everything I've seen recently it seems that most of what Thomas learned came later, and was then applied masterfully on the west coast.
