Collón Curá River

The Collón Curá River is a geographical feature of Neuquén Province, Argentina. It flows southward from the confluence of the Aluminé and Chimehuin Rivers, near the town of Junín de los Andes, for around 70 kilometres (43 mi), past which it becomes a tributary of the Limay River. The Collón Curá Formation and in turn the South American land mammal age Colloncuran are named after the river.
