The SE-flank of Nevado Piuquenes has been skied down by Peter Schön in December 2005, probably the first ski descent. He also determined the altitude of the summit by DGPS.

Marmolejo is one of the few places from where you can see the mountain in it’s
true size. © Photo taken by my friend Gerald Puffinger († Kobenz,
