The ruins of Ccorihuayrachina, in the Urubamba Valley, are very primitive and were 

 visited for the first time in 1912. Inside of one of the houses here shown is a solitary square 

 projecting stone, the only thing that diflferentiates these ruins from mnny others.

Corners of two of the smaller houses are shown in this picture as well as the type of 

 tent used by most of our parties. It has only a single pole and may be easily put up by one 

 man in five minutes (see text, page 534).
