The Mashco Piro uncontacted tribe are still living a nomadic Stone Age existence so far removed from modern civilization that they don't even know water freezes or boils, yet they can kill a person with a bamboo-tipped arrow shot from extreme range before the victim even realizes they've been hit.

And so this river has remained wild through the centuries. And even during the '90s when there was a mahogany boom where people went out for it,
