the steepness of the ice front and the amount
of loose supraglacial debris part of the snout
was not directly contoured. No altitudes,
therefore, were determined between the ab-
lation stakes (Ab, Fig. 1) and the front edge of
the glacier. Altitudes were determined along
the crevassed lateral slopes of the snout at
intervals of about 10— 15 m along lines spaced
25 — 75 m apart, the precise spacing being
dictated by the positions of the crevasses. Be-
cause the central lower portion of the glacier
could not be surveyed from any of the off-
glacier stations a station was established on
the ice (Ice Eu). During the survey the
positions of B.S.E.S. Stations 7 and 8 and two
ablation stakes were resurveyed and eight new
