Yasuni National Park in the Ecuadorian Amazon is shaped like a mechanical claw, or the open jaws of a craggy, prehistoric reptile. It grasps in its mouth roughly half of the land titled to the Waorani, one of the country’s indigenous nationalities. Peering down at the Google Earth view it’s impossible to tell where one might begin and the other might end. Dark green tree cover obscures a web of settlements, hunting paths, fishing holes, and water sources, making the area appear nearly empty. The Waorani describe the government maps of the area as similarly empty or “dead.” Using low-connectivity tools, they have begun mapping their territory as they see it, both for their own edification, and in case they need to defend their land rights.
