Over this valley only a 

 few small isolated hills 

 rise above the general 

 level. The bay seems 

 shallow save opposite 

 the Barra do Suape, 

 the only big break 

 in the reef, where the 

 scour of the tides has 

 kept the silts from 

 accumulating. 



The hills that face 

 the bay at the cape are 

 mostly crystalline 

 rocks, granites, gran- 

 ite-porphyries, and al- 

 tered eruptives, with 

 patches of Tertiary (?) 

 sediments lying over 

 and against them. 

 These hills are about 

 fifty metres high. From 

 the cape at the old fort 

 they strike westward 

 and after following that 

 direction for several 

 kilometres swing south- 

 ward and finally ap- 

 proach, but do not 

 quite reach the sea 

 again at Serramby 

 Point, some thirty odd 

 kilometres from the 

 Cape. These hills are 

 of pretty even elevation 

 where they are near the 

 coast, but nothing can 

 be said here of their 

 forms or elevation at 

 the west edge or bot- 

 tom of this ancient 

 embayment.
