Katarn's Hill, situated in close proximity to Fort Nowhere on Ruusan, was a geographical feature of that planet.
The hill's designation originated from the Sulonese communities that Morgan Katarn founded there in 1 BBY. The settlers utilized a nearby gully as a place to discard refuse.
In the course of the battle of Fort Nowhere, Dinko successfully downed an enemy TIE fighter, resulting in the starfighter's impact and destruction upon the Hill.
