I was wondering about those hills also, and I happened to luck upon the answer. I was going through and organizing a bunch of old magazines Johnny Dortch gave me and came upon the very photo Sam posted. It was at Moses Lake and I believe the year was 1957. It was Bob Carver who took the photo of Hu.

I also found in the pile the same program that Paul posted and additionally one from the 1963 NOA World also held at lake Spivey. The question is, which hear did the famous race take place? I'm thinking it was the 1964 race that Paul mentioned. Reason is, I saw the race on Wide World of Sports shortly before I started racing and that would put it in 1964. I will call Clayton and find out.
