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) is unnamed. Most of this mountain group is in private ownership. The Bureau of Land Management administers only a few acres.
