NO. 2 FRASER : SCIENTIFIC WORK, VELERO III, EASTERN PACIFIC 231 



Fig. 231 Two miles south of Tagus Cove, Albemarle Island, lies what is prob- 

 ably the largest crater lake in the archipelago. Although a mile or more 

 in length, it does not appear on any chart and must be located anew 

 by each expedition by means of directions handed down by preceding 

 expeditions. 



PLATE 111 



Fig. 232 Lava beach north of Tagus Cove, Galapagos. A grove of mangrove 

 trees indicates a lagoon on the right. One of the five large volcanoes 

 of Albemarle Island rises majestically in the distance. 



Fig. 233 Tagus Cove, Albemarle Island, the most protected anchorage in the 

 islands, but unfortunately too small to hold many vessels at one time. 

 Visiting ships have left their names whitewashed against the dark lava 

 rocks. Tagus Cove is the home of the Galapagos penguin and the 

 flightless cormorant. Chart 102, p. 418. 



PLATE 112 



Fig. 23+ The area around Christopher Point, Albemarle Island, is perhaps the 

 most desolate in the entire Galapagos. Here many small spatter cones 

 may be explored within a mile radius, provided one is fortunate in 

 arriving in one of those rare periods in which a landing can be made.

Fig. 235 One of the most massive single formations in the Galapagos archi- 

 pelago is this perpendicular headland at Cape Berkeley, Albemarle 

 Island. It is composed of volcanic ash and shows landslides resulting 

 from the undercutting. A fairly safe anchorage for the tuna fleet is 

 found close in at its base. (Photograph by H. W. Manter.) 



PLATE 113 



Fig. 236 Members of the 1938 Hancock Expedition explore a huge crack in the 

 misshapen mass of pahoe hoe lava at Cartago Bay, on the east side of 

 Albemarle Island. Mangrove trees form an almost impenetrable barrier 

 between the sand beach and the lava rock. 



Fig. 237 The Velero III anchored in Tagus Cove, Albemarle Island. The suc- 

 cessive beds of volcanic ash of which the island is composed are no- 

 where seen better than along the south rim of the cove. 



PLATE 114 



Fig. 238 Academy Bay, Indefatigable Island, showing houses in the middle dis- 

 tance which were occupied prior to 1938 by a Danish-American family 

 named Rader. A garrison of Ecuadorian soldiers was stationed at the 

 fort, which is known locally as Puerto Ayora. Chart 106, p. 420. 



Fig. 239 The large rock shingle at Barrington Island, Galapagos, was a profit- 

 able collecting ground for early Hancock Expeditions. The cactus- 

 studded interior of the island is the home of land iguanas, hawks, and 

 doves. Chart 106, p. 420. (Photograph by W. L. Schmitt.) 



PLATE 115 



Fig. 240 Conway Bay, Indefatigable Island, showing stretches of coral sand 

 separated by rocky promontories representing ancient lava flows. Such 

 beaches are the homes of the ghost crab Ocypode. Chart 107, p. 420. 



Fig. 241 Conway Bay, Indefatigable Island, Galapagos, showing Eden and Guy 

 Faulkes islands in the distance. The reef in the foreground was a col- 

 lecting station of the marine zoologists. Chart 107, p. 420.
