Steve Wilson,
Yes, the courses I am speaking of at Yorktown includes the one that Dan Wexler cites in his Missing Links book. I had assumed since the hotel wasn't completed that the golf courses were not built. Dan maintains that the shorter River Course was in fact built. The map that Dan drew in his book is very similar to the Flynn drawing that I have courtesy of David Gordon.
There are a few differences however (yardage, direction changes within holes, bunkering, etc.) that may be because the course was built not 100% according to plans as is often the case. One significant difference that should be pointed out is that Flynn indicated the use of "modern interrupted fairway construction" (segmented fairways) that he liked to use as a direct result of the Pine Valley influence (Flynn worked there in 1921) and is reflected in his design work of the early 20s. I'll have to speak with Dan and see if he drew his map from an aerial photo and if so, obtain a copy.
I did not imply that Mike Cirba was thinking of the merits of putting a golf course on the Valley Forge encampment grounds. I merely noted that the features found on such sites were interesting to him and had inspired him to find commonalities on existing golf sites. The fact that this mental exercise was extended further to actually include them in golf course design was an interesting find and so I started this thread. I, for one, am glad that the Yorktown battlefield is now back to a National Park as it should be and Valley Forge remains undeveloped. There are plenty of good sites for golf courses and hallowed ground should remain untouched by development.
Mackenzie's work in camouflage and recognizing the overt look of British military earthenworks without the camouflage concept employed by the Boers has had a profound influence on the natural appearance of man-made features on golf courses. Again, I did not mean to imply that Mackenzie wished to utilize military works in golf course designs, simply that the lessons learned in hiding the hand of man in such projects were useful in golf course design and construction.
