Although I have read most of the available books on Robert Scott's last antarctic expedition, this one added to my knowledge and understanding of what happened and why. I found the comparisons between Scott's expedition and modern day Antarctic travel both enlightening and disheartening, and honestly dreaded the back-and-forth-in-time aspect of this work. However, the interesting reflections on the effects of polar winds and weather (which have the benefit of years of data accumulated by man and machine), made up for any regrets I may have had about juxtaposing modern day science with Scott's historic march. Well done!
