MOUNT SALCAXTAY AND THE YALE GLACIER AT THE HEAD OF THE AOBAMBA VALLEY 



This peak, one of the most beautiful in the Andes, is probably 21,000 feet above sea- 

 level, and has never been climbed or triangulated. It was cloud-covered so much of the time 

 that we have hitherto been unable to triangulate it. Clouds may be seen gathering m front 

 of the glacier, and two minutes after this picture was taken the entire mountain was envel- 

 oped in cloud, and nothing more than partial and fleeting glimpses were had of it during our 

 stay in the vicinity (see pages 539, 541. 560, 564-565)-
