Impressive pics, but as mentioned, capturing undulations and elevation change is very difficult in photographs. This course has an abundance of both.
Brian Silva has been the restoration consultant and continues such. Keith Foster is not involved in the work. As for original design, Macdonald was indeed the architect with Raynor providing the engineering: the dramatic greens (particularly 2,3,5,6,7,10,13,14,15 and 16 - Ran has a good synopsis of each) are the best indicator that CBM spent time at St. Louis.
The 15th hole ("Narrows") has a double plateau (not biarritz) green; the 5th is called "Punchbowl" - due to the green which indeed was returned to its original spot in the early '90s. No. 18 is an Alps hole, but is called "Oasis".
SLCC is a very special place and those that are lucky enough to play there realize that CBM left a gem.
