The group reached Plaza Argentina (14,000ft) yesterday, after a 3 day hike through the Relinchos Valley. This is the place where the climbers begin to acclimatize to altitude.
Rolo, the lead guide, said that everybody is fine and did it great! Today they will rest and enjoy the food there.
The plan is to carry the loads to Camp I tomorrow and return to Base Camp to sleep. That is the carry-move-rest system that they will use from now on to gain altitude.
We attach a picture of Polish Glacier, in the East Face of Aconcagua, the view from the approach to Base Camp
We will keep you posted
