Abandoned in the Arctic

The documentary cleverly juxtaposes the original expedition led by Adolphus Greely with one in which Greely's great-grandson retraces his steps. Both journeys run into unforeseen problems, and the element of suspense adds to the already extreme sense of adventure.

Thanks to technology and better luck, the practical and human challenges for second expedition were less harrowing than the ones faced by the first one. What's most surprising is that so much graphic documentation remains from the first journey, which dates back to 1881-1884.

It's fascinating adventure story, grippingly told.
