The Colors of Quebrada de Humahuaca
May 23, 2012
Just outside the town of Purmamarca, the Secretary of Tourism and Culture of Jujuy Province posted a display of large photographs and geological information.
Here is the English translation:
What we commonly call the Seven Colors Mountain is the outcropping of some rocks in different times, the result of the interaction of huge forces in the terrestrial cortex and its erosive processes which belong to the region called Easter Mountain Range. The variety of colors is the product of the accumulation of sediments in the nautical and continental watersheds for some 600 million years.
