(Answer: You are in the leached cap; go deeper). Let’s face it: relying on a poorly scanned,

Until the Levinson estate releases a legal digital edition, the search will continue. But remember the lesson of the book itself: If you cannot find the primary source (the PDF), look for the secondary halo (the modern textbooks, the SEG archives, or the used bookstore). The anomaly is there. You just have to know where to grid.
