Ryan, your 1937 aerial changes my understanding of the original amount of trees that existed after L&M laid the course out. I was under the impression from the drawings I have seen that far less trees existed originally surrounding 13 green and the narrow corridor of trees down to the par 3, 14th. But if this is a 1937 aerial, those trees didn't grow in a mere decade from a sparsely treed area I thought it to be to the numerous treed one that is shown on the aerial.
I hope Dan Moore weighs in on this. And this also confirms my recollection of sand in the diagonal bunker on 6 from my childhood excursions there. Just this last weekend we were wondering if there was a sand bunker behind the boxcar hole and my recollection was that there was also sand there back in the late 50s-60s.
After this 1937 aerial, it is clear that many more conifers were plugged into the corridors during 50s60s. A load of the were put in up the right to make more of a dogleg look on 9, to the right of the right FW bunker of the driving line off the tee. And, load of conifers were planted between 11 and 13.
Another surprise is that the 1937 aerial shows not pond at the bottom area below the approach on the left up to 13th green site and down to the left off the tee on 15. Instead, a bunker down there is shown. Also, my memory of the deep valley on 13 where the second lay-up must then cross the valley and up steeply to the green had always had a drain way or what you might call a seasonal wet-season creek/drainage. But, it doesn't appear in 1937 to be as significant a seasonal drainage as I remember it 50s-60s.
While the de-treeing which now has removed all the green surrounding turf stunting 13th and narrow corridor 14th par 3; original design was not treeless as I previously thought. That means the de-treeing project over the last few years in that sector is not restoring, it is remodeling. Perhaps remodeling to a sympathetic ideal of what the links 'should' look like.
It was the right thing to do, at any rate, IMHO.
Thanks Ryan.
BTW, what is obviously the clubhouse in the 1937 aerial, looks like the same old seasonal clubhouse, which was a white painted wood sided building with an old black painted screen door with one of those long springs, that I can still here in my memory slamming as people went in and out...
