National Geographic : 1913 Apr
Photo by Hiram Bingham CCORIHUAYRACHINA 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 differentiates these ruins from many others. Photo by Hiram Bingham ANOTHER GROUP OF RELATIVELY UNIMPORTANT RUINS VISITED FOR THE FIRST TIME IN 1912 WAS AT LLACTA PATA IN THE AOBAMBA VALLEY 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).
