Thanks everyone for the contributions on this interesting subject.
It would seem that there is still some slight haze over the exact reason, or circumstance as to how this actully happened...though a little bird landed on my shoulder late last night and informed me that it was in fact years and years of 'extreme' topdressing. I am not not completely sure what to take as gospel at the moment and no explanation will likely lead me this way anyway for too much history has taken place. Nevertheless, there seems to be some solid evidence stemming from the reconstruction of the surfaces from old to more modern profiles as well as the long standing position of unusual topdressing practices.
I'll buy that as good enough for government work, until such time any other definitive evidence surfaces in the coming days, but I still find it most unusual to see this having happened at such a remarkable and historical venue, don't you agree!
Paul: thanks for calling upon your 'higher powers', it will be interesting to hear if they turn up any other thoughts.
Jeff: that was my first odd thought as well. If the profiles were sand anyway, why would they topdress so much, and if they were converted not all that long ago, historically speaking, how could so much be added?
Wayne: I have the answer to solve all of this. How about we sneak into the grounds some warm evening this spring while the ground is still soft and take our shovels and simply dig around in a couple of those babies and uncover the "REAL" truth. We'll be hero's man... mythbusters!!...just think of it...allright, who's with us on this! Set your watches to 5 tango, zulu, zulu, bravo, 7, we leave at dawn men! OUT!
