SCOTT'S LAST EXPEDITION
[October

From the Glacier Tongue we still pushed north. We reached Dunlop Island on the 24th just before the fog descended on us, and got a view along the stretch of coast to the north which turns at this point.

Dunlop Island has undoubtedly been under the sea. We found regular terrace beaches with rounded water-worn stones all over it; its height is 65 feet. After visiting the island it was easy for us to trace the same terrace formation on the coast; in one place we found water-worn stones over 100 feet above sea-level. Nearly all these stones are erratic and, unlike ordinary beach pebbles, the under sides which lie buried have remained angular.

Unlike the region of the Ferrar Glacier and New Harbour, the coast to the north of C. Bernacchi runs on in a succession of rounded bays fringed with low ice walls. At the headlands and in irregular spots the gneissic base rock and portions of moraines lie exposed, offering a succession of interesting spots for a visit in search of geological specimens. Behind this fringe there is a long undulating plateau of snow rounding down to the coast; behind this again are a succession of mountain ranges with deep-cut valleys between. As far as we went, these valleys seem to radiate from the region of the summit reached at the head of the Ferrar Glacier.

As one approaches the coast, the 'tablecloth' of snow in the foreground cuts off more and more of the inland peaks, and even at a distance it is impossible to get a good view of the inland valleys. To explore these over the ice cap is one of the objects of the Western Party.
