Uwe, you put up four very interesting pages. However, they are almost identical and there doesn't seem much to put them apart. Why not elaborate the specifics of the mountains a bit more in the overview sections, e.g. a bit more about the routes, which one you did, if there are other ones, if there are technical routes, etc.
Please add a signature photo, add the peak to the "Puna de Atacama Group" and make the links live.
A route would be of help.
I also agree on what Gangolf says and one error that have to be corrected is the fact that you state the peak is located on the border of Catamarca and La Rioja provinces.
The peak is firmly placed in La Rioja.
Tell me when updates are made and I'll up the vote.
