Joe/Wayne,
You guys are getting ahead of my winter project; that is, finally getting down to the Hagley Museum to trace the design evolution of Cobbs Creek.
Frankly, I want to see if it's possible for the course to be restored to the original design.
This is what I know so far;
According to Tillinghast, it was designed by Hugh Wilson, assisted by A. Haseltine Smith of Huntingdon Valley, another prominent amateur. Tilly also gave much credit to the original Super for building the course, although I don't have his name in front of me right now.
The original plan was discarded and wholly revised because it was thought to have too many blind shots for a public course.
The Karakung course opened in 1927 with 11 holes in play. I suspect that similar to Juniata, which also opened in 1927, it was designed ("laid out" is the words used to describe) by Parks Engineer Alan Corson, with input from local pros like Edward Clarey (first pro at Juniata who also worked with Corson on FDR Park (FKA League Island GC)) and "the input of local golf architects", which at the time would have likely been guys like Flynn, Findlay, and perhaps Wilson before his untimely death in 1925. All that being said, Corson was the guy who was ultimately responsible for the plan of Juniata, FDR, and probably Karakung.
The holes on the Cobbs Creek course that are original (according to Jim Finegan) as Wilson laid them out include 1, 2, 3, 4, 7, 15, 16, and 18 and he claims four others are very similar.
This is sometimes confusing because I've been there where the first two starting holes are on the clubhouse side of the road and also when the clubhouse side holes play as 17 & 18. Finegan's numbering has the clubhouse side holes as 17 & 18.
I also believe it's possible that some of the original course is part of today's Karakung course, although a trip to the Hagley should indicate whether that was true.
