Peter Mather and the filmmaker hauled a combined weight of 700 lbs in equipment in 4 pulks behind them in order to intercept the Porcupine Caribou migration.
After skiing for 18 days, unable to speak to each other while in transit due to the deafening sound of the pulks grinding in snow, filmmaker Marty O'Brien finally found the missing iPod in his equipment pack with Game of Thrones audio book ii loaded onto it. From this point on the pair argued over who's turn it was to listen in order to avoid the tortuous sound of the pulks and sense of isolation.
