The team is at high camp tonight and planning to head for the summit early tomorrow morning! They’ve done great and it sounds like everyone is feeling good about a summit attempt tomorrow. High camp is at nearly 19,000 ft, so they’ll be moving slowly and feeling the altitude tonight. The camp sits on a ridge that separates the Vacas Valley approach from the normal route on Aconcagua, so from this camp they will descend the other side of the mountain and out the Horcones (normal) route.
Wish them luck for their summit push in the morning!
