Photographer's Note

Some pictures from Brazil reminded me Argentina, so this time I jump to Andean village Purmamarca. The villages origin can be traced back to the 16th century when it was part of the Inca Road. The only way to go there from Salta and to see some places was to go for a tour with the local agency. It was nice excursion. The main attraction of Purmamarca is this hill behind that is called the Hill of Seven Colours (Cerro de Siete colores).

Sprung up around seventy-five million years ago, the hill was formed by a complex geological process that involved deposition of sea, lake and river movements and subsequent elevation of the land due to the movement of the tectonic plates. The hill is called such due to the various pigments acquired by the minerals that make up the sedimentary layers.

This breathtaking sight is composed of 7 different colours, all of which derive from different types of rocks; leading to its diverse range of colours. Each colour/rock is also said to have formed during different time periods. Firstly, pink is believed to be composed of red clay, mudstone (mud) and arilitas (sand). Its estimated age goes back about 3 to 4 million years. The shade of white surrounding the pink is mostly made up of limestone and is aged about 400 million years. Continuing onto the mix of brown and purples, which are composed of lead, and rich in calcium carbonate, and is 80 to 90 million years of age. On top of the purple-brown colour, there is an earthy brown colour that has been detected in the rock. The rocks making up this colour are the most recent colours appearing on the rocks, aging at 1 to 2 million years old, and is described as fanglomerate composed of rock with manganese belonging to Quaternary. As for the red, which is composed of claystones (iron) and other clays belonging to the upper Tertiary, its said to also be aged around 3 to 4 millions years. The shades of green, aging at about 600 million years, are made up of phyllites, and slates of copper oxide. Finally, the yellow mustard colour is made of sandstones with sulfur, and is estimated at 80 to 90 million years.

After I upload this picture I noticed that my attempt to get rid of the wires was not successful, as Chris pointed out. Next time I must work harder. :). Another thing. Do you see something like the pieces of wood on the right and left side of the girl? These are cacti!
