The guide of the 7 Summits Club Artem Rostovtsev reports from Argentina:
Yesterday-today on Aconcagua. We went up to the Nido de Condores camp. We are almost not tired. We even managed to sleep well. The forecast was for the whole day 90-100km/h along the summit, and we need to complete acclimatization by walking at 6000m. So we packed up and went out thinking that if it gets really bad, we'll be back in half an hour. However, we returned after 4 hours, reducing the plan quite a bit, we did not reach 50 meters in height. Now the group is already resting under the howling wind in the Plaza de Mulas. The forecast for the next few days looks so-so, but we will try to conjure.
