Nice! That looks like an amazing place.
We used to through the Manso from Arg. down to the Puelo as a three day trip. And remember the talk of the road to be built. But not of the dams.
Unfortunately that's how it goes. They get everybody stoked by talking about a new road, but then the ulteror motive is to put in a dam to serve the big cities that are nowhere near and make $ for the Spanish company Endesa.
Hopefully that doesn't get buried. I'm pretty sure the Bachelet government wouldn't let it happen.
