THK WESTERN precipices: machu picchu 



Forest trees growing wherever there is a foothold have usually been found in this 

 region to cover ancient agricultural terraces, and they probably do in the cases shown in 

 this picture. The western trail to Machu Picchu climbs out of the canon in the lower right- 

 hand corner and winds up the precipice until it passes over the shoulder near the top of 

 the precipice.
