Fig. 44—The snow-capped Cordillera Vilcapampa 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.


Fig. 46—Hacienda Huadquiña in the Salcantay Valley a short distance above its junction with the Urubamba, elevation 8,000 feet (2,440 m.). The cultivated fields are all planted to sugar cane. The mountain slopes are devoted to grazing.
