ON A ROCKY RIDGE THEY SKIRT A DANGEROUS ICEFALL About the time the trio made this noonday halt, 5,500 feet up on the lower spurs of Crillon, an avalanche thundered down from the glacier before them; its debris can be seen at the right. Because of the danger from such avalanches, most of the back-packing of supplies had to be done along narrow ridges separating the glaciers. Up one side of rocky pinnacles and down the other the men clambered, carrying heavy loads (see page 391). MOVIESON THE ROOF OF ALASKA The author trains his camera on the summit ofMount Crillon from asteep slope above the highest camp. Ski-pole rings were used on the legs ofthe heavy tripod to keep themfrom sinking deep into the soft snow. At midday the temperatures below 8,000 feet were rarely cold enough inclear weather to necessitate very heavyclothing; infact, for hard jobs the men often stripped to the waist (seeillustration, page 373).
