204 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 1 



PLATE 99 



Fig. 208 The ruins at Pachacamac, visited by hundreds of tourists annually and 

 included in the itinerary of a party from the Velero III at the time of 

 1938 cruise to Lima, Peru. 



Fig. 209 Expedition photographer surrounded by white-breasted cormorants at 

 Chinchas Islands, Peru. Elevation of Middle Chinchas is said to have 

 been lowered over 100 feet in the removing of its crown of solid guano. 



PLATE 100 



Fig. 210 (A panorama.) The north island of the Ballestas group, Peru, taken 

 from near the summit of the south island. The Velero III may be dimly 

 seen immediately above a large patch of nesting birds located over the 

 sea cave which is a prominent feature of the middle island. 



Fig. 211 The Ballestas Islands, among the most eroded of the Peruvian guano 

 islands. They support guanayes and piqueros in about equal numbers, 

 the guanayes preferring the more level, the piqueros the more sloping, 

 localities as shown on the promontory to the right. In the distance rises 

 the cloud-enveloped summit of the island of San Gallan. 



PLATE 101 



Fig. 212 From the summit of Mazorca Island a magnificent panorama of ocean, 

 rocky shore, and mist-filled valleys unfolds, the Peruvian Andes serv- 

 ing as a backdrop. The birds in the immediate foreground are piqueros, 

 those on the lower slopes guanayes, or white-breasted cormorants. 



Fig. 213 View of Independencia Bay, Peru, taken from the east side of Vieja 

 Island, looking south. The Humboldt penguin burrows into the recent 

 conglomerate stratum of the beach in the foreground. In the left back- 

 ground is the Peruvian mainland. Chart 96, p. 415. 



PLATES 102, 103 



Fig. 214 (A panorama.) A view of the peninsula which forms the southern 

 boundary of San Juan Bay, Peru, southernmost locality visited by the 

 Velero III. The Peruvian sea lion inhabits the rocky coves shown at the 

 right of the picture, the Andean condor flying above the precipitous 

 bluffs. Chart 97, p. 416. 



Fig. 215 Rugged coast encountered off San Juan Bay, Peru, showing rookeries of 

 the Peruvian sea lion, and large beds of kelp. The rocks in the distance 

 make navigation exceedingly hazardous. 



Fig. 216 San Juan Bay, Peru, most southerly point visited by the Allan Hancock 

 Expeditions. The Expedition launch is about to land at a seal hunters' 

 camp. A desolate portion of the Peru coast line is shown on the other 

 side of the bay. 



PLATE 104 



Fig. 217 View of Viejas Island, Peru, looking across the southern channel of 

 Independencia Bay from Santa Rosa Islands. The Santa Rosa Islands 

 are a much eroded, uplifted plain, the summit of which affords nest- 

 ing sites for thousands of white-breasted cormorants. Chart 96, p. 415. 



Fig. 218 The various islands of the Santa Rosa group are connected by sus- 

 pension bridges which greatly facilitate the work of the guano har- 

 vesters. The islands are the remnants of an uplifted, wave-cut bench. 



Fig. 219 The Santa Rosa Islands, located at the southern end of Independencia 

 Bay, Peru, and devoted exclusively to the culture of the guanaye or 

 cormorant. Across the channel may be seen the southern end of Viejas 

 Island, the summit of which is shrouded in mist.
