But no one had actually gone down into the actual site of the boundary of creation as we call it -- into the Rift Valley -- until a group of seven of us crawled in our little submarines in the summer of 1973, 1974 and were the first human beings to enter the Great Rift Valley.
但没有人能真的下去， 进入那个撕裂的边界的现场 进入我们称为大裂谷的地方—— 直到1973年和1974年的夏天，我们一行7人爬进小潜艇， 于是，我们成为进入大裂谷的第一批人。
