Frank Hurley's *Endurance* photos/videos (a sampling from YouTube)

--> At around the 6 min mark, the *Endurance* collapses into the ice

--> Notice, also, that Hurley, not two of his shipmates, is credited with retrieving some of the negatives from the sinking ship...

--> Lastly, there is a useful graphic toward the close of this video clip representing the party's drift on the pack ice and the narrow window of opportunity (and thus proof of Worsley's metal as a keen navigator) to make landfall.
