Ice is a subject that rewards attention. It records climate, shapes coastlines, kills the unprepared, and has drawn expeditions for as long as there have been maps with blank spaces at the ends. Hidden World of Ice places Laurel Melmed on that ground, filed with us under science and engineering alongside sport and the outdoors.
That pair of shelves is a useful clue to the register. It points to something positioned between the laboratory and the field: not a technical monograph, but not pure adventure writing either. Four hours is roughly the length of a good long documentary, which is often exactly the right size for a subject you are curious about rather than committed to.
