Follows the life of David Hopkins, a geologist, whose curiosity and leadership resulted in a large, collaborative effort among scientists from many disciplines to propose, debate and discuss the Bering Land Bridge. The book presents the story of the land bridge as a mystery, revealing different lines of investigation, facts, and controversy regarding the natural history of the area between western Alaska and Siberia, which is thought to have played a major roll in human, animal and plant migration through geologic history. The story includes other key figures who contributed to the effort, and also shows some of the workings of the scientific institutions as the debate about the land bridge unfolds. Well written, includes maps and pictures of people and places where discoveries were made. ( )

This worked out well for a bargain bin purchase. It's like a tribute to Dave Hopkins, the scientist who figured out how the land bridge thing worked. All the science parts are clear and interesting for non-science people like myself, and I learned all sorts of cool things about Alaska. For instance, I never knew that the land bridge was something that would come and go at various times, I guess I had the impression that it was a one-time thing. The whole lack of megafauna (in modern times, that is) is depressing to me, though. It's so unfair! I mean unfair to me, personally. I would be so excited about a mammoth, it's so dismal that I will never see one.

Grade: B+, this was very good, although I suspect people who already know a lot about geology and um, the history of weather, or whatever you would have to know about to know about the ice ages, would find it too basic.

Recommended: To armchair naturalists, it reads a lot like a very long article in Smithsonian Magazine, and to people who like mammoths. I also happened to read it while that Into the Wild movie was being talked about a lot, and so I noted that Last Giant would be a good choice if you wanted to read a book about someone who went into the wilds of Alaska and actually did something useful.
