first of all, sorry to answer you so late!! I┤ve been without internet for a long time, but I┤m still on TN.
You should visit it: you can see a picture, someone can talk about it but that is nothing since the moment you are looking at it, hearing the water pounding, feeling the nature power... I cryed that time, it┤s too hard to understand what you are looking at. I hope (and I send you my best wishes) that you can visit it. (at this time, I become your trip planner into Argentina, jajaja First you go to Iguaz˙ and the you come to do some treks on Patagonia!)
Thank you again for look at the pic and comment on it,
have a nice weekend,
