 Fig. 63 Shore line north of Laguna Beach, California, consisting of a number 



of shallow bays separated by cliffed promontories. (Photograph by 



C. McLean Fraser.) 



PLATE 29 



Fig. 64 Guadalupe Island dwellings constructed of native volcanic rock. The 

 Mexican government maintains a garrison for the protection of the 

 elephant seal herd on the other side of the island. Chart 13, p. 371. 



Fig. 65 The south end of Guadalupe Island affords a glimpse of the effects of 

 volcanism. A cap of lava overlies the stratified deposits of earlier 

 geological periods. It is as if one were viewing the inside of the rim 

 of a crater, the major portion of which had been worn away, allowing 

 access to the crater by the sea. 



PLATE 30 



Fig. 66 A portion of a herd of nearly 1,500 of the northern elephant seal, bask- 

 ing on a lava beach at the foot of a talus slope. Behind them the shore 

 of Guadalupe Island rises precipitously to a height of 4,500 feet. 



Fig. 67 The protected west shore of East San Benito Island, breeding ground 

 for thousands of California sea lions. The sandy slopes to the right 

 afford nesting places for western gulls and California brown pelicans. 

 Chart 39, p. 391. 



PLATE 31 



Fig. 68 Wreck of a south-bound tanker aground almost at the foot of the light- 

 house on West San Benito Island. An ancient shore line is distinguish- 

 able at a higher level. 



Fig. 69 The village on the east side of Cedros Island, located on an alluvial fan 

 which represents the third and last of 3 periods of fan formation, the 

 long slope in the distance being the first. (The principal occupation of 

 the inhabitants is the canning of lobster and abalone which abound on 

 near-by rocky shores.) 



PLATE 32 



Fig. 70 Algae on shore, South Bay, Cedros Island, Mexico. The conspicuous 

 form with the branching stalk is Eisenia. The finer growth in the fore- 

 ground is eel grass (Zostera). (Photograph by Wm. R. Taylor.) 



Fig. 71 The landing at South Bay, Cedros Island, a region of great interest to 

 the geologist, who reports that its formations are precretaceous meta- 

 morphics and quaternary volcanics. Chart 40, p. 392. 



PLATE 33 



Fig. 72 Beds of Macrocystts off shore, Thurloe Bay, Lower California, Mexico. 

 Thurloe Bay marks the southern limit of large kelp beds. The rocks in 

 the foreground represent a series of tilted sediments. (Photograph by 

 Wm. R. Taylor.) 



Fig. 73 Turtle Bay, Lower California, Mexico, showing conglomerate rock in 

 the background and beds of kelp among which collecting was accomp- 

 lished on an early Hancock Expedition. Chart 42, p. 393. 



Fig. 74 Rocky coast of Asuncion Island, Lower California, a favorite breeding 

 ground of the California sea lion. The incessant barking of thousands 

 of these animals made sleep impossible aboard the Velero III anchored 

 a mile off shore.
