There was a point on the first page of Andes that made me freeze in horror at what the remaining 500 pages might contain. It wasn&rsquot landslide, a volcanic eruption, climbers succumbing to hypoxia, nor popular culture&rsquos best-known Andean tragedy &mdash the Uruguayan rugby team who survived a plane crash and wished they hadn&rsquot. Jacobs says that his interest in the range had been stimulated by stories of his grandfather who had worked there as a railway engineer before World War II. Hell, I thought, it&rsquos going to be a &lsquoJourney into the Past&rsquo, the &lsquoJourney into Oneself&rsquo. I&rsquod prefer a long walk off a short pier to one of those. Thankfully, I was dead wrong. Jacobs&rsquo journey is informed not by soupy family anecdotes, but the writings of authors and explorers who&rsquove been there before him. Accounts of Alexander Humboldt&rsquos eighteenth-century expeditions and the travels of Christopher Isherwood are oft-quoted.
