conforming closely to the irregularities of the underlying rock. These glaciers may 

 end either in a snout, in which case they look just like a slab of ice plastered against 

 the clift', or, in the case of the slightl)' larger ones, in a small ice-cliff high 

 above the sea. 



Mackenzie Peninsula. 



The glaciers here were not closely investigated. They appeared to be in the 

 main separate ice-sheets completely cut off from each other by the steep central 

 hill ridge and lateral spurs, and in all cases ending in an ice-cliff at high-water 

 mark. Solid rock was visible below the ice-cliff in places. The ice-sheet at the 

 head of Wilton Bay extends round on to the base of the west side of Mossman 

 Peninsula, where it forms a narrow, steep ice-foot glacier between the central 

 dividing ridge and the sea. There is a small spit or snout interrupting the cliff 

 face near its southern end. This ice-sheet does not extend far from the head of 

 the bay, being limited by a sharp rock wall, and south of this point the slope is too 

 steep for anything beyond one or two cliff glaciers. 



Mossman Peninsula. 



On the Scotia Bay side of Mossman Peninsula there is a glacier extending a 

 great part of its length. The south-west side of "The Beach" is bounded by a 

 line of cliffs about 400 feet in height, with a small plateau between them and the 

 central ridge. On this the glacier starts. The remainder of this ice-sheet has 

 already been described (see pp. 851 and 856). 



Mount Ramsay. 



This is a good example of a flat-topped mountain covered by an almost completely 

 cut-off ice-cap from which small avalanches are not uncommon both in winter and 

 summer. 



Scotia Bay Ice-sheet. 



Many of the features of this glacier, lying to the north and east of the Scotia's 

 winter quarters, have already been described. Above Point Moreno, where a spit 

 interrupts the cliff face, lies what we usually spoke of as the " N.E. moraine." Very 

 probably it really is loose rocks on the top of a nunatak just emerging from a 

 ridge extending down from the spur above to Point Moreno. The ice slopes fairly 

 well up the main ridge of hills to the north. This ridge is cut across by two cols, 

 one filled with the ice leading to the glacier on the north coast, east of Uruguay 

 Cove, the other at a higher level to the ice-sheet on the west side of the base of 

 Pirie Peninsula. The slope up to this latter col is easy and even on the Scotia 

 Bay side, but on the other the descent is steep and terraced, and probably in the 

 height of summer would be found to be badly crevassed, although as late as the 

 end of November we found no difficulty in crossing through.
