Query: Great story, flawed method.

Reading the other reviews of this book, I'm reminded of a quote from one of my favorite, although little known Sean Connery movies, where he plays an Arab pirate. At one point Connery says to his second in command: "It is good." "What is good?", replies the other man. "It is good to know where we are going," answers Connery. Alas, Herzog and his men didn't know where they were going, and spent a month wandering around looking. It would have been good to send out an initial recon group to find the mountain before they started out. Or, to paraphrase an english adventurer, "to lose a pack animal is unfortunate; to lose an entire mountain seems downright careless."
