PLATE 61 



Fig. 129 George's Island, Gulf of California, is the nesting site of thousands of 

 Brewster's boobies and lesser numbers of red-billed tropic birds. Chart 

 64, p. 402. 



A quiet inlet on the southeast shore of Tiburon Island, Gulf of Cali- 

 fornia, home of the nomadic tribe of Seri Indians. A dwarf species of 

 deer is said to occur on the island, which is exceedingly barren, moun- 

 tainous, and with no apparent sources of fresh water. Chart 66, p. 403.

PLATE 62 



Fig. 131 The south shore of San Esteban Island shows a type of undercutting 

 by wave action which is characteristic of the unprotected shores of the 

 Gulf of California. The ship's launch is shown in the foreground. 

 Chart 66, p. 403. 



Fig. 132 San Pedro Nolasco Island is located in the Gulf of California north 

 and west of Guaymas. There are few landing places on its steep granite 

 slopes. It is inhabited largely by pelicans, boobies, and rock iguanas. 

 Chart 67, p. 403. 



PLATE 63 



Fig. 133 One of the several boulder-strewn canyons which rise precipitously 

 from the eastern shore of San Pedro Nolasco Island, Gulf of California. 



Fig. 134 Mainland of Sonora, Mexico, seen from the shores of San Pedro Nolasco 

 Island, Gulf of California. 



Fig. 135 The Sonora coast line north of Guaymas is exceedingly irregular. 

 Perhaps no landmark in the entire Gulf is more distinctive than las 

 tetas de cabra shown above the ship's telegraphic control. 



PLATE 64 



Fig. 136 Puerto San Carlos, a small landlocked bay in the vicinity of Guaymas, 

 Sonora, affords ideal protection to small vessels. Velero III anchored 

 outside in the larger Ensenada de San Francisco. 



Fig. 137 San Ignacio Farallon is located in the southern portion of the Gulf of 

 California about 18 miles from Topalobampo Harbor. (Like Consag 

 Rock, it seems to bear no relation to its surroundings, the mainland 

 territory being low and sandy.) Expedition members scaled the summit 

 and found thousands of nesting sea birds, including tropic birds and 

 Brewster's boobies. Chart 68, p. 403. 



Fig. 138 The las tetas de cabra is a particularly eroded pinnacle located within 

 sight of Guaymas, Sonora. Hancock Expedition scientists scaled all but 

 the topmost pinnacle on two separate occasions. Chart 13, p. 371. 



PLATE 65 



Fig. 139 Panoramic view of the harbor at Guaymas, Sonora, showing cargo ves- 

 sels in the foreground and the city in the middle distance. The boat 

 landing is to the left of the cathedral spires shown above the lowest of 

 the signal flags. Chart 13, p. 371. 



Fig. 140 Beach at Mazatlan, Mexico, just west of the harbor, showing break- 

 water extending to Chivos Island in the center, in back and to the 

 right of which a freighter may be seen. Chart 13, p. 371. 



Fig. 141 Entrance to the harbor at Mazatlan, Mexico. The lighthouse is perched 

 upon Creston Island at the right, fully 500 feet above the surface of 

 the sea.
