From Halopedia, the Halo wiki
The Karfu Mountains border the northern Uldt Desert. Gila Station is located in the eastern portion of the border. The Carstolum River used to run through the mountains from north to south before it dried up, leaving nothing but a river bed behind. At some point in the past, the Unwavering Discipline and other ships, belonging to Thars, crashed in the mountains.
