For me, Frank Cabot was always somebody whose garden I wanted to see. And I never got a chance to do so until about 15 or 16 years ago when I met some people who knew him quite well and they said, "Well, we'll introduce you to Frank Cabot, and you can look at the garden.” When you first come to this garden... you are absolutely knocked out by the way in which he's used the over 20 acres that he has. And this area after all was created from everywhere, from Les Eboulements to here, was created by an asteroid. That's what caused the hills to come up and so on. And I think we have that magic feeling that this was created out of time and space.

위 단락 중 " That's what caused the hills to come up and so on."이 뭔 소린지 선뜻 이해가 안됩니다.
