The Beacon Valley camp (fig. 1) was located on a small patch of snow on the southwestern flank of University Valley (1650m; S77°51.368′ E160°41.987′) and was selected for the snow patch and central location to the valley. However, due to the rugged terrain and subsequent slow walking, it probably would have been more convenient and as climatically comfortable to camp adjacent to the main valley bottom on the southeastern flank. Winds during the field visit were generally down valley and less than 10 knots, however, diurnal up-valley winds were also encountered.
The Arena Valley camp (fig. 1) was located at the western end (generally the leeward end) of a linear snow patch at the northern edge of Ashtray Basin (1130m; S77°51.593′ E160°56.915′) and was selected for the snow patch and central location to the valley. Winds, generally down valley, were 10 – 15 knots stronger than Beacon Valley during the field visit and probably averaged between 15 and 25 knots. Wind strength and duration at this location was about average for the valley floor.
The Pearse Valley camp (fig. 2) was on an alluvial terrace located at the eastern edge of Lake House (325m; S77°42.101′ E161°26.924′) and was selected for its proximity to a source of water. Wind direction and strength seems highly variable throughout the valley and diurnal variations were common. During the field visit, winds did not exceed 20 knts and seemed strongest from 2 – 5 am. In general wind strength and duration were inbetween those of Beacon and Arena valleys.
