What is "sjoa"

The Sjoa river provides the outlet from lake Gjende at Gjendesheim in the Jotunheimen mountains of Norway's Jotunheim National Park. It flows eastward into the Gudbrandsdalslågen river via the Heidal traditional district in the Gudbrandsdal.

South of the village Randsverk it flows through Ridderspranget—a ravine named after a Norwegian myth.
