Great report. After reading most of your exotic trip reports, it's funny to scroll through the pictures on this one and find my neighbourhood!

You did manage to squeeze many things during your trip. Next time you should definitely visit Patagonia. I was last in Iguazú almost 15 years ago and your pictures make me want to go back. Why did you cross to Paraguay? Asunción grows on you, but Ciudad del Este is dystopian.

The mummies in Salta were part of a (small) national debate when they were put in that museum. The mummies were found hidden on Mt Llullaillaco, right at the border between Salta and Chile. The Llullaillaco is an active volcano (the world's 2nd highest active volcano after the Ojos del Salado, which is some 200 km south) and many people, particularly in the native communities in the North, argued that the mummies were placed there for some reason -- i.e., as part of an agreement with the Mountain to prevent eruptions. It's like the Mountain said "give me your children and I will stay quiet". The Llullaillaco last erupted in 1887 and the mummies were taken out of in 1999, but the discussion continues. Respecting Mother Earth is a big thing up North.

Glad to read you enjoyed your time in Argentina!
