This tall amphitheater (Quebrada de Cafayete) is a natural rock formation created by El Rio de las Conchas. The light enters from a narrow opening above and swirls around the carved walls. The rock walls glitter from embedded minerals and casts an overall glow of soft bronze. The mother and child on the bottom of the canyon give perspective to the height of this mesmerizing structure. Calchaquies Valleys, Argentina. January 2014.
