I’m a little tired, so I’ll make this brief. This image is of a rock form called “Cara del Indio”, which translates to english as “Face of the Indian” – because the rock form resembles the profile of face of a wizened old Indian; the native people of this area were the Mapuche, who were mostly wiped out by the Spanish Conquistadors. The word “Futaleufu” by the way, is a Mapuche word that translates as “Big Water”, and yes indeed, the Futaleufu River is Big Water. Chile.
PS – Oh, I should’ve added: this feature is just before Mundaca. Generally rafting trips will pull over on to a small beach below Cara del Indio, have a quick rest, and the guides will go over the plan for running Mundaca – it also allows the safety boats, like the cataraft and a kayaker or 2, to get ahead and set up for safety, if needed.
