Photo by Hiram Bingham A BURIAL CAVE AT MACHU PICCHU The first burial cave discovered at Machu Picchu containing a human skull. The picture was taken after partial excavation, showing the skull still in place. In all, more than Ioo such caves were opened and a large quantity of skeletal material secured. Photo by Hiram Bingham THE SAME CAVE FROM A DISTANCE OF 20 FEET: MACHU PICCHU It was extremely difficult to find these caves. Here is a picture of cave No. I from a distance of only 20 feet. The entrance to the cave is near the center of the picture. It may be imagined that not the least portion of our difficulties was the cutting of paths through this dense tropical jungle and the transportation of material from the caves in which it was found. This cave was on the side of the mountain about 800 feet below the city of Machu Picchu (see pages 446 and 447).
