Tasman Glacier, and it is not surprising, therefore, that by some judges Sefton is preferred to Aorangi as a view.
The supreme ambition of quite a number of Southern Alpine climbers has been the ascent of Mount Cook, but comparatively few have scaled it. Aorangi is difficult to climb, and there are times when the guides at the Hermitage will not undertake the ascent owing to dangerous ice conditions. From the hotel the average round-trip length of Mount Cook ascents is from four to five days, but as weather conditions are uncertain a week or two may be required sometimes. From Cook the sublimest view of the Alps is obtained. On clear days even Mount Aspiring, a hundred miles away, is visible.
The Hooker River Valley, into which we were to descend, was dark with glacial accumulations. For the greater part of its length it was partly filled by the Hooker Glacier, seven and one fourth miles long, and to a smaller extent by the Mueller Glacier, eight miles long, which flowed into it at the base of Sefton.
