A flashlight view of the interior of the largest cave, at the base of one of the great 

 precipices of Huayna Picchu. The cave is nearly go feet in length and is partly lined with 

 cut stones. It had long been known to the Indian treasure-hunters of the neighborhood, 

 and consequently yielded no results (see pages 446-447 ')•
