"Do I get an "A"!!!"
Not even close Richard. Go to the back of the room and sign up for extra tutoring if you wouldn't mind.
I believe Pine Valley is at a corner of what is broadly known as the New Jersey "Pine Barrens." Perhaps you've never heard of it but it was not an area that farming was ever done. When I explain it to you perhaps you may figure out why but I'm not counting on that yet.
The New Jersey Pine Barrens is a large area of basically pines and massive amounts of extremely sandy soil that apparently due to that happens to sit on an enormous stock of some of the world's purest water. They say that New York and those north have had, in the past, a very covetous eye on that massive store of pure water probably somewhat as Southern California covetously eyed and eventually used Northern California's water.
For this reason that site was clearly never farmed unless they had some transplanted Americans from Scotland who were under the impression one could farm on straight sand.
The ultra sandy soil makeup of Pine Valley was apparently also why C.B. Macdonald famously mentioned to Crump and Pine Valley that the course might be one of the greatest in the world if they could figure out how to grow grass on it! Macdonald should've know of what he was saying considering the mighty struggles he had growing grass at NGLA before realizing he had to truck thousands of cart-loads of topsoil onto it and cover the whole place.
When Crump came to find out what he was up against in that vein he was known to famously say when one asked what he would like for Christmas-----"As many truckloads of topsoil as you can spare me." (Part of his agronomic problems apparently was he was using liberal amounts of low area "muck" in its place.
Pine Valley also sits on what is known as the "Cohansey Strata"----eg also a massive store of pure water.
No sir, Ricardo, I'm afraid you get an "F" for "Failure" on this one!
Let me help you out with some informed speculation. I would say the trees on the site of Pine Valley when Crump found it probably were that small due to a massive forest fire probably not much more than a couple of decades previous. The only other logical alternative theory I can think of is it may've been massively logged in the previous decades as much of Long Island was in the 18th and 19th centuries.
