What a pity!
We camped ther in 2006 and was one ot the highlights of the trip, simply for being very peaceful (we were the only people there!!), as well as very beautiful, with the Rio Claro (IIRR) rushing by.
But as Sime66 pointed out, this is nature at work and I can accept it far more easily than something being ruined deliberately in the name of making money as can happen in the world.....
That does not make it easier on the Chilean people and we both hope they are back to life as normal as soon as possible.
Adventure: it's an experience, not a style!
(so ride what you like, but ride it somewhere new!)
