Quebrada de las Flechas, Natural canyon formation on Route 40 in Salta, Argentina
The sedimentary rock formations rise 150 feet high, creating angular walls and sharp peaks throughout the 20-kilometer stretch of the Calchaqui Valley.
Archaeological evidence reveals an Inca fort established near Angastaco around 1414, positioned strategically on the right bank of the Calchaqui River.
The ancient Tucumanahao temple site, significant to the Calchaqui nation, stood in this area until its destruction in the early seventeenth century.
Travelers should plan their visits during autumn, spring, or winter, maintaining speeds under 25 kilometers per hour on the gravel sections of Route 40.
The rock formations display color variations from pale ash to reddish ochre, transforming their appearance as sunlight shifts throughout the day.
