Sawtooth Range, Mountain range in central Idaho, United States
The Sawtooth Range is a mountain chain in central Idaho featuring over 50 peaks rising above 10,000 feet, dominating the landscape with jagged, tooth-like ridges. The terrain spreads across hundreds of miles with steep slopes, deep valleys, and snow-capped summits visible throughout much of the year.
The mountain range formed through two distinct geological events: the northern section was shaped by the Eocene Sawtooth batholith, while the southern part was influenced by the Cretaceous Idaho Batholith. These two geological formations created the distinctive structure and composition of these mountains over millions of years.
Ernest Hemingway spent his final years near this mountain range and chose the town of Ketchum as his home, making the region a destination for those interested in his legacy.
Access to this mountain range is mainly through trails and camping areas that remain open year-round, though summer offers the easiest conditions for exploration. Winter snow makes many higher elevations difficult to reach, so visitors should plan their activities based on the season.
The area holds around 400 lakes created by ancient alpine glaciers, with waters flowing into major river systems such as the Salmon and Payette Rivers. These numerous mountain lakes form a distinctive feature of the region and shape its hydrology fundamentally.
