When I played Doral (before the renovation), I asked a guy in the pro shop what total elevation change was. He said twelve feet. Not sure if that's right or not, but I'll bet there's some course somewhere with less.
A couple of questions:- What's the great elevation change on a single hole (anywhere)? Par 3? 4? 5?
- Is there a course where the highest and lowest points on the property are on the same hole?
There are probably plenty of courses with around 10-12 feet of elevation change, but not many with less than that. You've got to have somewhere for the water to go.
The property for The Rawls Course had THREE feet of elevation change to start with.
I don't know the answers to your other questions. I doubt anyone has a definitive answer to any of them ... most would be found on awful courses. On a top-100 course, the most elevation change I can think of is 110 feet, from the 10th tee at Augusta to the low in front of the green, but it's possible there are a couple I'm not thinking of on newer courses. Going uphill, there are two holes at Pasatiempo that climb 90 feet from tee to green, the 9th and 11th.
Your latter query is possible, if an architect was starting with no elevation change and wanted to maximize the impact of his earthworks; but I don't think you would ever find the natural high and low of rolling property that close together.
