Bill, Alex, Its hard to tell from the schematic if that right side is fairway. I know at one time it was, but, it may have been nixed by 1929.
Alex is correct that the green's more receptive from the angle the right side provides, especially if one is incapable of carrying a towering approach shot over the fronting left bunker, from a downhill lie. The hillside to the left of the green was/is steep enough to allow for a bounce, but nowadays, with the long rough and lush conditions, highly unlikely.
The first hole is very interesting with the left side bunker. Currently, the left side has only a bunker in the front. But it also now has a chipping area where the back half of bunker in the schematic resides.
As I understand it, the teeing ground was originally back down at grade, approx. where the practice putting green is, or, at least where the wall of fame now exists. If that's true, the uphill nature of the hole would've been accentuated, making this opener no slouch. The angle, shape and orientation of the let fairway bunker is different today, but, it's placement is likely similar.
The 8th hole is very curious indeed, without the bunkers along the canyon rim well short of the green.
