Morning sunshine causes the snow to become less stable for walking, and increases avalanche risk from 8 am onwards. The views on a clear morning from the summit are unbelievable - the mountain is far higher than anything else anywhere nearby, and the Cordillera Real, Lake Titicaca, La Paz, and part of the Altiplano they reside on are all visible. Until early 2004 there was a guest book for summitting climbers to sign. Unfortunately this overhang collapsed in mid-2006 leaving the original metal container protruding out of the summit ridge hanging above the city of La Paz below.
