The undercover video, filmed by NBC News, reveals women and children among the thousands who hack away in sub-zero temperatures for hours on end.
In the footage, the slave work gangs shovel the fresh snowfall with makeshift tools to clear the route to Kim Jong-un's pet project – the Masikryong Ski Resort.
Thousands of red-faced slave labourers endure blizzard conditions and freezing temperatures while smashing at the snow with pickaxes and sticks.
A small group of uniformed soldiers can also be seen keeping guard of the roadside mountain workforce.
