From the Edge: Season 1

Episode 5

Winter Extremes

Glacier National Park, Montana

Peter leaves his cowboy hat at home and favors a ski mask as he heads to Montana in the heart of winter. In conditions that would drive an Eskimo indoors, the Master Photographer treks through frigid landscapes - and even scales a 400-foot frozen waterfall - to capture the unique beauty of Big Sky country as the mercury plummets.
