HIS I9II LXPLDITION to PERU 
The ruins are on an almost inaccessible ridge, 2,000 feet above the Urubamba River. 
They are of great beauty and magnificence and include palaces, baths, temples, and about 150 
houses. The huge blocks of white granite, some of them 12 feet long, were so carefully cut 
that they match perfectly. Though no mortar or cement was used to hold the stones together, 
the walls have withstood the elements for at least 2,000 years. The stone against which the 
man in the upper cut is leaning is 13.2 feet in length and about 2.8 feet in thickness.
