Bob Vladem called in after the team pushed up to 20,000′ on the north ridge of Aconcagua.  They were fortunate to have good weather and moved up under clear skies with light winds.

The route up from Camp 2 first climbed up a steep hill immediately above camp.  This led them to a long section of old, “dead” glacier that is largely indistinguishable from the rocky mountainside in a few places, where the ice, buried under much scree, is visible.  The hiking is pleasant, although the climbers are definitely noticing that altitude!  They are now breathing air that has just under half the amount of oxygen as does the air at sea level, so everything is harder.
