About Ninety Percent Range
The Ninety Percent Range is a remote and rugged mountain range located in central Idaho. Stretching over 30 miles, the range is characterized by steep, rocky peaks, deep glacial valleys, and expansive alpine meadows. The terrain is largely untouched, with few developed trails or access points, making it a true wilderness destination. The geology of the range is dominated by ancient granitic and metamorphic rock formations, shaped by glaciation over thousands of years.
