South side of Bore valley, slopes towards Pot Harbour (Grytviken). 
The difference between the different sides of the pass in Bore valley plainly 
shows the influence of exposure on the vegetation. In a climate so little favourable 
to plant-growth as that of South Georgia, exposure plays a very great part. On 
the south slopes the snow is much more easily accumulated, the vegetative season, 
short enough before, is considerably shortened and little direct sun-shine is enjoyed.: 
This is sufficient to produce an Antarctic tundra, small patches of mosses between 
snowdrifts and piles of stones. Only scattered individuals of the Acaenas, Festuca 
and Phleum were found.
