I respect the fact that it has been a week at this height of more than 5000 meters. The highest I've been, and no more than an hour, was at Peak Espejo (4.765 metros), "at Peak Bolivar" in Venezuela, and at that time I felt the weight of the height with a heaviness in my head. .. Now, the image is spectacular and the description you make is very good, it really has no loss ... Greetings.
