HIGH SNOWFIELDS OF THE ST. ELIAS MOUNTAINS YUKON TERRITORY, CANADA.

Abstract

Observations made during the 1964 summer provide a description of snow and radiation characteristics for the region and give insight into effects of altitude, regarded as a gross variable, when anomalous wind and slope effects are excluded. Divide Camp, Seward Camp, and Lucania Camp were occupied successively within a minimum period of time to compare conditions at different altitudes. Data are presented on snow profiles, snow accumulation measurements, the development of the annual snow layer, snow conditions at depth, the mechanical properties of the snow, snow densification, solar radiation, and the variation of snow properties with surface altitude. It is concluded that as long as local anomalies are avoided, the effects of surface altitude on snow properties and surface processes seem to be simple. However, in mountain regions it is probably a combination of local conditions which produces the most remarkable effects. (Author)
