We got up early this morning and made a river crossing to begin heading up a small side valley towards Plaza Argentina. Hiking temperatures were really nice and we had the occasional breeze to help keep us cool. Aconcagua dominated our views during most of the day. The team arrived in base camp this afternoon and quickly settled into camp life. Dinner was a delicious meal of spare ribs and grilled vegetables. We’ll be spending a few nights here as we adjust to the altitude and prepare for the upper mountain.
