PLATE 37 



Fig. 80 The landing place at Los Frailes is a sandy beach behind the granite 

 promontory which marks the northern limit of the bay. The ranch 

 house is located a few hundred yards to the interior, and some of the 

 higher mountains of the cape region are shown in the left background. 



Fig. 81 Promontory of massive granite which marks the anchorage at Los 

 Frailes. Granitic rocks were encountered at the tip of the Lower Cali- 

 fornia peninsula and again at Granite Island, off the north end of 

 Angel de la Guardia Island, near the head of the Gulf. 



PLATES 38, 39 



Fig. 82 A panorama showing the complete west side of Espiritu Santo Island, 

 Gulf of California, and including within its scope Ballenas and San 

 Gabriel bays. The picture was taken from a small, nameless island in 

 La Paz Bay. Chart 52, p. 397. 



Fig. 83 Spectacular headland located on the west side of Espiritu Santo Island, 

 Gulf of California, showing clearly the result of bedding. 



Fig. 84 The Isthmus of Espiritu Santo Island, Gulf of California, showing the 

 bay at low tide and giant cacti in the foreground. 



Fig. 85 At extreme low tide heads of coral and encrustations of worm tubes are 

 bared in the shallow bays along the east coast of Espiritu Santo Island, 

 facing the larger La Paz Bay, Gulf of California. An Expedition mem- 

 ber is here shown digging the hatchet clam or Pinna. Chart 51, p. 397. 



Fig. 86 Sandstone headland on the west side of Espiritu Santo Island, south of 

 San Gabriel Bay, Gulf of California. The bluff shows stratification and 

 brilliant coloration. Its flat top is suggestive of volcanic capping. 



PLATE 40 



Fig. 87 San Gabriel Bay, Espiritu Santo Island, a shallow inlet of La Paz Bay 

 backed by a mangrove-encircled lagoon, the outlet of which is shown 

 at the right of the picture. A narrow arch of beach separates the lagoon 

 from the bay. 



Fig. 88 San Gabriel Bay, Espiritu Santo Island, Gulf of California. The white 

 sand is backed by mangrove trees behind which rise mountains of sedi- 

 mentary origin capped by harder volcanic material which has retarded 

 their disintegration. 



PLATE 41 



Fig. 89 Lighthouse at Prieta Point, Lower California, marking the entrance to 

 the harbor at La Paz. The mountains in the background were once 

 continuous with those of Espiritu Santo Island to the north. Chart 51, 

 p. 397. 



Fig. 90 Beach at La Paz, Lower California. The city itself is situated on a 

 shallow lagoon shown at the right. Vessels of large draught must 

 anchor outside, off Pichilinque Harbor. Chart 51, p. 397. 



PLATE 42 



Fig. 91 View of Agua Verde Bay, Lower California, from the north shore. One 

 of the secluded bays in which collecting was done may be seen in the 

 background, another in the background to the left of the Velero III. 



Fig. 92 View of Agua Verde Bay from the north shore showing village site 

 along the margins of the wash in the right background. The slope in 

 the foreground adequately represents the chief types of vegetation on 

 the dry hillsides in the vicinity. Chart 54, p. 398.
