Abstract: 

Between 29 August and 1 September 1981, four snowpits were dug on the East Ridge of Mount Egmont at elevations of 1240 m, 1370 m, 1580 m and 1980 m. Snowpack structure at all four sites was characterized by alternating layers of coarse melt-freeze grains and ice bands, with essentially isothermal temperature profiles in all pits. Depth of snow, snowpack water equivalent and integrated ice band thickness display strong positive relationships with elevation. These features of snowpack structure and properties reflect strongly Mount Egmont's maritime climate, particularly the effects of periods of above-freezing temperatures throughout the winter and the occurrence of rain-on-snow.
