Fig. 44 — The snow-capped Cordillera Vilcapanrpa north of Yucay and the upper 

 canyon of the Urubamba from the wheat fields near Chinchero. In the foreground 

 is one of the well-graded mature slopes of Fig. 123. The crests of the mountains lie 

 along the axis of a granite intrusion. The extent of the snowfields is extraordinary 

 in view of the low latitude, 13° S. 



Fig. 45 — Rounded slopes due to glacial action at Pampaconas in the Pampaconas 

 Valley near Vilcabamba. A heavy tropical forest extends up the Pampaconas Valley 

 to the hill slopes in the background. Its upper limit of growth is about 10,000 feet 

 (3,050 m.). The camera is pointed slightly downhill.
