The return south retraces the canyon at a different pace, the familiar formations now lit from the opposite side. The final stop before Cafayate is Los Médanos marks the southern end of the quebrada proper — a crescent of pale sand dunes up to 15 metres high, an incongruous deposit of desert in the middle of red rock country. The dune sand is composed of fine quartz and mica, and the same mineral composition contributes to the Cafayate terroir — the mica reflects heat back upward into the vine canopy from below, concentrating sugars in the grape. The connection between the geology underfoot and the wine in the glass is direct.
