The Ninety Percent Range is the southernmost extension of the Blackfoot Mountains. It extends southeast from the Chesterfield Range to Soda Springs. The smallest named mountain range in Idaho, roughly 7 miles long and 3 miles wide, it is a mountain range in name only. It is in reality a ridge attached to the Soda Springs Hills. The highest point, 6,851 feet in altitude, is unnamed. Most of this mountain group is in private ownership; the BLM administers a few acres.
