The Magnificent Quebrada de Las Conchas
The Quebrada de las Conchas (also known as the Quebrada de Cafayate or the Gorge of the Shells), is a dramatic brick and ocher-hued landscape located in the Calchaqui Valleys of northwest Argentina. Ninety million years ago, this area was covered by a huge inland sea, and you can still see the remains of seashell fossils studded into the carved rocks, hence the name, Gorge of the Shells.
