The South Ridge, also known as the South Slope, was a section of the Clabburn Range mountain range situated on the frigid planet of Hoth. Following the Battle of Yavin, the Rebel Alliance constructed a concealed base known as Echo Base, and this ridge was directly to its south. During the Galactic Empire's attack on Echo Base, the South Ridge served as a staging area to coordinate the escape of Rebel transports, in addition to the starfighters assigned to protect them as they broke through the Imperial blockade of the system.
