text: I'm pretty sure that this is where the Fitzcarrald Ishtmus (Istmo Fitz-Carral) is located. The other place currently tagged as that location is not an Ishtmus, it's just between two tributaries of the same river. Satellite data of this new point also shows a clearing of trees, making it more likely as the real location (even though abandonment of the Ishtmus as a trade route decades ago should have overgrown it completely).
