Jökla is a large river (150 km) that flows through Efri-Jökuldalur (upper valley) and characterizes the place with the separation it creates. There are many stories of when the people who lived on either side of the river had to communicate but could not cross the canyon because of the river Jökla. Then they shouted across the canyon and they say it is a certain art to shout over the canyon and not something that everyone can learn how to do. They had to think of how sound travelled across with the wind, so they needed to be situated correctly and of course shout loud enough. In conversation with the habitants in the area it becomes clear that they feel a strong connection to the river and they often personify the river. One habitant said for example that when they started preparation for Kárahnjukar dam; “I feel like something will happen, maybe she will get revenge somehow “.
