T HE close relationships between diverse types of terrain make the McCall Valley area a particularly interesting one for the ecologist, geologist and geomorphologist. The McCall Glacier, which occupies the upper part of the valley, heads in a region of high serrate granite peaks (2,290 to 2,740 m. above sea-level) and ends in a narrow V-shaped valley that opens into the wider Jag0 River valley. The tundra, characterized by its vegetation and lack of sharp relief, begins approximately 5 km. from the glacier ter-minus on the north side of Marie Mountain (see map Fig. 7) at an altitude of 900 m. This rapid transition from icy peaks to vegetated plain within short walking distance is extremely attractive, both scientifically and scenically. Previous exploratiens It is not known if the McCall Valley had been visited prior to 1957; however, in the early 1900’s a prospector, T. H. Arey, travelled along the Jag0 River from its mouth at the arctic coast to its headwaters, bringing back reports of glaciers existing in its western tributary valleys. E. de K.
