I found this 1938 aerial of The Country Club. At the time of this photo the club was nearly 50 years old so I am unsure if this is how the course was originally routed or if there had been some modification to the routing prior to the date on the photo.
One of the things that stuck out in the 1938 photo is the multi use of what I assume is the polo fields and a few golf holes. Also obvious over the last 70-80 years is the expansion of the existing ponds, changes to some of the bunkers and some fairways were narrowed.
Below is a comparison of the 1938 to 2016. I was able to line these up almost perfectly to make the comparison a little easier. The black and white photo is the 1938 aerial and the color photo is the 2016 aerial.
Take a look for yourself and let me know if you see anything else.
After looking at the The Country Club, I may take a deeper dive into the topography if the data is available.
