Quebrada de las Flechas (Canyon of the Arrows) is a amazing natural rock formation in the Valles Calchaquíes with eroded cliffs in all kind op tones that rise out of the terrain like gigantic arrowheads. Rock formations with astonishing shapes jut out to 50 meters from the valley floor. These rock formation dates back 15 to 20 million years when large blocks of rock began to rise. These strata were folded and fractured when they received the push of the Andes mountain range. Later erosion sharpened them and now they resemble blades or arrowheads side by side. The famous Ruta Nacional 40 ( www.ipernity.com/doc/294067/49276088 ) is running through this lunar-like landscape between the towns of Cachi and Cafayate, near the village of Angastaco.
