Stratigraphic Studies of the Winter Snow Layer, Mount Logan, St. Elias Range

A traverse of King Trench, which rises from Upper Ogilvie Glacier (2300 m) to King Col (4500 m) a distance of 16 km, Yukon Territory, was made for US Army CRREL, June 1965, to see if techniques of stratiographic analysis of snow and firn could be successfully applied to studies of the alpine climate...
