Cedar Valley is northeast trending. It narrows in the southwest, between mountain ranges; in this southwest section, the Harmony Mountains are west, and the Hurricane Cliffs are east, bordering the Kolob Terrace. The valley is mostly about wide, between mountains, or ranges, or the Hurricane Cliffs, to the east, which is a 75-mi long landform, from Hurricane, Utah at its southwest end. The valley's north and northwest terminus merges into the Mud Spring Wash-Rush Lake region at the southwest of the Black Mountains, ; a ridgeline extending southwest from the Black Mountains parallels the Hurricane Cliffs, and its terminus is at the north end of Cedar Valley. Between the ridgeline, and Hurricane Cliffs, east, Interstate 15 traverses,. It is also the route of the former Old Spanish National Historic Trail. The Historic Trail traverses the Cedar Valley from Enoch in the northeast, across the center-north to exit through the hills northwest, and through the townsite of Iron Springs, between the hills, and on the southeast edge of the Escalante Desert.
