  • I don't know much about this kind of books, but do you know "No Bone Unturned"?

    September 11, 2008

  • I liked it. It's old, though, and now I'm interested to find a similar book that's more up-to-date, so I can see if there have been any new discoveries in these particular cases since publication. For some (e.g. cholera, Robert the Bruce), probably not. But yes, it's well written and interesting.

    I suck at book reviews.

  • “The astonishing fact was that Mawson had taken forty-six days to drive himself on foot nearly 300 miles through the worst wilderness known to man, navigating by means of a damaged theodolite balanced on the corner of the cooker box, a compass rendered unreliable by the proximity of the South Magnetic Pole and a watch which had stopped at least two or three times. Though he kept a careful tally of his estimates for his daily marches, he had been reckoning progress by a sledge cyclometer that repeatedly jammed and broke. Yet here he was returning to base within 300 yards of his predicted line of travel.�?
