The Peninsula between Liefde Bay and Wijde Bay. 



On the east side of Liefde Bay, where 1 was ashore, perhaps 12 kilo- 

 metres south of Grey Hook, there is a sk)ping platform cut in solid rock 

 (see Fig-. 152), l)Ut its upper level is very much higher than the strandfiat 

 of Reindeer Land. PVom a vertical shore-cliff, about 10 or 11 metres 

 high, backing a flat l)cach, there is a relatively steep ascent to a sharply 

 marked shore-line cut in solid rock 41 metres above sea-level. It is 

 marked by a horizontal series of small accumulations of snow (see Fig. 152) 

 and is backed by a vertical shore-cliff about 6 metres high. From the 

 edge of this cliff, 47.25 metres above sea-level, there is agam an ascent 

 to 62.25 nietres above the sea, where a relatively broad plateau extends 

 southwards along the foot of the steep mountain side (see Fig. 153). The 

 foot of the steep scree along the inner margin of this plateau stands about 

 4 to 8 metres higher, i. c. 66 to 70 metres above sea-level. On the plateau 

 ihere were indications of a shore-line marked by a series of snow- 

 accumulations (see Fig. 153, along the middle of the plain, towards the 

 mountain slope) . 



The surface of this plain consisted of loose material. The highest 

 level at which solid rock was observed was that of the shore-cliff at about 

 47 metres above the sea. This may be the actual height of the rock plateau, 

 which may, however, rise gentlv to a few feet more under the layer of 

 loose material at the foot of the mountain side. 



To the north of this place, where we made our measurements, there 

 was a lake (see Fig. 154) lying at a lower level. On the north side of
