PLATE XXVI 



Bristol Island (cont.) 



Fig. I. Freezeland Peak, the land sighted by Cook when he discovered 

 the South Sandwich Group in 1775. The rock is seen from the N, the 

 summit bearing 165°, distant 7 cables. The great pillar on the right, 

 900 ft. high, is thought to be of sedimentary rock, while the lesser peak 

 on the left is possibly metamorphic. 



Fig. 2. Another view of Freezeland Peak, seen from the SW, with the 

 summit bearing 045°, distant 5i cables. The slopes of talus on this rock 

 are the resort of large numbers of penguins. Wilson Rock and part of 

 Grindle Rock are seen in the background. 



Fig. 3. Wilson Rock, 500 ft. high, seen from the SW, the summit bear- 

 ing 060°, distant 5J cables. This rock is entirely composed of black 

 columnar basalt. 



Fig. 4. Grindle Rock, 700 ft. high, seen from the W, the summit bearing 

 090°, distant 3 cables. The rock is mainly composed of the reddish and 

 yellowish tuffs which are a characteristic feature of most of the islands.
