I've read a good selection of books on polar exploration, and I found this to be well written - very interesting and exciting. It was over a decade after the "golden age", but though they did use a little more modern technology than in the classics of Amundsen, Scott, and Shackleton, the journey recounted here is very much in the same mould. A good adventure story, set it in the barren icefield of Greenland, rather than the Arctic or Antarctic. It also discusses other adventures of Watkins before and after the main event, and has some interesting analysis of his leadership style. It was remarkable to hear how the other members of the expedition went on to lead some remarkable trips of their own, but how some of them ended up meeting quite tragic ends - lives lived to the fullest, but still unfulfilled.
There were a few things that stood out as negatives, though they probably reflect more the state of modern historical writing than errors of this author. One is we get some speculation on whether Watkins was a homosexual, based as far as I recall, on virtually no evidence. And the treatment of the Greenland native culture is a bit ridiculous. Roberts treats their legends of the beasts that inhabited the interior with the utter seriousness, as demanded by cultural relativity. We can not just face the fact that they were totally ignorant of the landscape just a few miles away, and gripped by deep and dark superstitions of what lay there. Roberts regard the 20th century Englishmen has rather ignorant and prejudiced when they call the lifestyle of the Inuit dirty. In modern times, I suppose cleanliness is no longer next to godliness, and we can't say a clean house is any better than a dirty hovel. Is there no chance they just honestly recorded what they saw? And finally, most concerningly, modern sexual ethics means that we can't imply any shame or wrongdoing or abusiveness to the fact that the expedition members took native girls as mistresses during their time in Greenland.
One final fact I found fascinating, touched on briefly, is that there is good reason to think that the Vikings found Greenland uninhabited, settled there, and then centuries later were attacked and exterminated by invading Inuit. Turns the traditional narrative of the settlement of the Americas on its head.
