List "Bighorn Basin" By JerryBrekhus Notes: The Bighorn Basin is bounded by the Absaroka Range to the west, Owl Creek and Bridger Mountains to the south, and Bighorn Mountains to the east. The north is not so distinctly bounded, so this list uses the Montana state line. Suppose for a moment that the Montana line to the north and Wind River Canyon to the south are both closed. The lowest way out of the basin is then an unnamed pass at 6290 feet between East Kirby and Bridger Creeks in the Bridger Mountains. This list uses the 6290 contour to define the west, south, and east limits of the basin.
