I have heard and seen the same explanation on the History Channel I think.
But anything is possible. Chicago is built on a swamp and I think the bedrock is even deeper than the area you are talking about. Deep caissons socketed into bedrock can do wonders for tall buildings where the bedrock is far below the surface. It is more expensive I imagine though.
