I´ve skied a lot, and could post some pictures of that, but this is sweet, too.
At 5493m, Cerro Chimbote is one of the highest unclimbed mountains left in the Andes. Its extremely remote location on the Chile Argentina border and technical summit towers have kept its summit virgin. I really want to go back there, but there´s hardly any snow this year so I might try to come back to it later. Also in the same area, equally remote is the 6000m Volcán Tupungato.
Here´s a photo of Chimbote I snapped yesterday while touring around Valle Nevado. The approach used in this trip report http://www.perrosalpinos.cl/relatochimb ... chert.html starts from not too far from where this picture was taken. Its far. There are some canyons back there with roads but access it tightly controlled by mines. You could get permission ideally to shorten the trek, even to use snowmobiles. Chimbote is the lower (looking) peak on the right. To the left is Cerro Tronco (I think).
