There are no other rocks remotely similar in shape in that river valley… [It] is perched perfectly overlooking a valley, and presides over a waterfall and a basin that resembles an amphitheater… There are markings all over [it] that indicate it was hacked out with rudimentary tools… There are actually two Rostros – a Rostro within a Rostro – look below the nose… The boulders along the river are arranged in a way to channel the flow away from hitting the [Rostro’s] face directly, and in a way that would make it impossible for the face formation to have been caused by impact from even the heaviest of storms… The Harakbut don’t have a written history, but claim the Rostro has been in their oral history for generations and generations.
