Unnh River

The Unnh River was located on Yavin 4 and was likely named for the Sullustan explorer Dr'uun Unnh. The river wound its way through the Wayward Jungle, the Isle of Kun, the Val'Arnos Jungle and the Ersham Ridge, passing close to the Palace of the Woolamander and the Great Temple. The stream formed a river delta, known as the Taurin Delta, as it entered an ocean. The Temple of the Blueleaf Cluster was located atop the Taurin Delta.

During the Galactic Civil War, the Mining Outpost and the Imperial Fortress were built near the river banks. The Yuuzhan Vong built their base along the Unnh River in 26 ABY, during the Invasion of Yavin 4 of the Yuuzhan Vong War.
