Along the escarpment on the western side of the Gulf, where tfhe aaatjve- 

 ment was greatest, certain blocks of sedimeolaiy material -have beea Sfted 

 into islands, or volcanic outbursts adjacent have made islands, such as 

 Ceralbo, Carmen, etc. 



South of La Paz earth movements, caused by several piefigure lines, 

 have thrown up jumbled strata, forming a very rugged granite triangular 

 area along the eastern coast, and which has in it various vokank intru- 

 sions formed deposits of precious metals, and which rise to 3,000 to 4,C00 

 feet altitude. This area is east and northeast of Triunfo .(44 miks ^onth

 like the flange of the letter L, though nine of Uiem instead of one^ 'H^cy
