Mike Hendren,
For a coastal FL course, I LOVED Camp Creek. I think it is one of those borderline courses that can rate any where between 75 and 200 modern. However, not being a rater, I am probably wrong.
As to the site, I spent a bit of time there and I was told that it was pretty flat in its natural state. According to management, the elevation changes and low-scale dune formations you witnessed were largely man made. I don't have my notes here in CA, but I think I verified this information by observation and non-related party accounts.
