In the north the small mountains at the northeast of the Mineral Mountains divide the valley into a northwest section, and a northeast section, (the route of Interstate 15 to Sulphurdale).

In the valley's center and south, the widest section is about 12-mi wide.

[2] The south end of the valley borders an east-west stretch of the Black Mountains, at its northeast terminus region; I-15 traverses southwest past the mountain range, and into the northeast of Parowan Valley.

Interstate 15 traverses the center sections of the valley, north-south.

From Beaver, Utah State Route 153 transits eastward, and enters the Tushar Mountains through Beaver Canyon, and traverses the center-south of the Tushar range.
