Pay the man, Shirley...
Dan,
Scale helps a lot. These photos don't show much ground contour, especially on the greens. These, as others taken for the Soil Conservation Service in the 1930s and 40s, are about 1:20000. These are also a couple steps removed from the original negatives which reduces detail even more. At 1:20000 scale and sun directly overhead elevation changes are almost entirely flattened out. What you're left with are bunker positions and shapes which sometimes are giveaways, especially for some architects. Green shapes may be misleading because by the late 30s they may have shrunk.
However, I've seem some SCS photos where it's possible to see very good detail - relative bunker depth, mounds, ridges and internal contours on greens. Other sources - the Dept. of Defense photo archive for example, often have photos taken at a much lower altitude - I've seen some taken at 1:2500.
For example, I had one photo taken of a course in NY that I could not identify. I knew the area but since I couldn't find an existing course that matched, I assumed it was NLE. The detail was excellent and I showed it to Ron Forse - he quickly guessed that it was a Ross design - based on the green contours and bunker positioning. He was right, the course was Hudson River CC located north of Yonkers.
