Chris:
Most of the responses are close.
I submitted about ten different possible cover photos from my collection. (One of the other possibilities was a photograph of the 8th at Cruden Bay, which later made it onto the cover of The Confidential Guide.) Sadly, the eleventh hole at Pacific Dunes didn't exist back then.
An art director looked at the various photos and picked the PGA West hole as his first choice. The publisher liked it because he thought it had all the elements of a golf course which I had talked about in the book (water, bunkers, green, psychology, esthetics, etc.). I was a novice and went along with their instinct.
I did not work on the construction of the Stadium course at PGA West, but I did draw the original plan for the course for Mr. Dye in 1983.
