A cold wind from the high Andes cuts through the van as it turns onto the dirt road toward Embalse El Yeso. The reservoir opens like a pale sheet of turquoise between steep granite slopes; loose scree cliffs and scrub pines frame the water while distant ice still clings to shadowed cirques. Guides point out a tunnel, a roadside waterfall and the faint line of an ancient glacier that once chiselled the valley.
