The Sawtooth Range is a mountain range of the Rocky Mountains in central Idaho, United States, reaching a maximum elevation of 10,751 feet (3,277 m) at the summit of Thompson Peak. It encompass an area of 678 square miles (1,756 km2) spanning parts of Custer, Boise, Blaine, and Elmore counties, and is bordered to the east by the Sawtooth Valley. Much of the mountain range is within the Sawtooth Wilderness, part of the Sawtooth National Recreation Area and Sawtooth National Forest.
The mountains were named for their jagged peaks.
There are 57 peaks with an elevation over 10,000 feet (3,000 m) in the Sawtooth Range, all falling between 10,000 to 10,751 feet (3,048 to 3,277 m) on Thompson Peak, the highest point in the range. Another 77 peaks fall between 9,000 and 10,000 feet (2,700 and 3,000 m).
Climbs range in difficulty between the 9,150-foot (2,790 m) Observation Peak, a Class 1 hike, and 8,980-foot (2,740 m) King Spire, a rock route rated Class 5.10 on the Yosemite Decimal System.
The northern Sawtooth Range formed from the Eocene Sawtooth batholith, while south of Alturas Lake the mountains formed from the Cretaceous granodiorite of the Idaho Batholith. AD. Evidence of past glaciation given remnants of the glaciers such as glacial lakes, moraines, horns, hanging valleys, cirques, and arêtes.The Sawtooth Range has a history of alpine glaciation, but while no surface glaciers exist today, perennial snow fields and rock glaciers remain, usually on north or east facing slopes. There have been 202 perennial snow fields mapped in the Sawtooth Range. The Sawtooth Range was last extensively glaciated in the Pleistocene, but glaciers probably existed during the Little Ice Age, which ended around 1850
In 2010, scientists from Idaho State University discovered the Sawtooth Fault near the base of the mountains, running for 40 mi (64 km) near Stanley and Redfish Lake. The most recent large quakes along it occurred around 4,000 and 7,000 years ago. It is estimated the fault could produce a 7.5 magnitude earthquake, potentially felt as far as Boise.
The Sawtooth Range is home to hundreds of lakes created by vanished alpine glaciers, with nearly 400 lakes in the Sawtooth Wilderness.Five of the six largest lakes in the range are located outside the wilderness (Redfish, Alturas, Pettit, Yellow Belly, and Stanley lakes), while Sawtooth Lake is within the wilderness.
Most of the east side of the Sawtooth Range is drained by the main stem of the Salmon River and the west side by the South Fork Payette River. Small portions of the northern and southern ends of the range are in the watersheds of the Middle Fork Salmon River and Boise River, respectively.
There are 40 trails totaling nearly 350 miles (560 km) in the Sawtooth Wilderness that can be used for day hiking, backpacking, and horseback riding and accessed from 23 trailheads. Additional trails traverse the foothills of the mountains outside the designated wilderness. Camping is permitted anywhere in the wilderness. There are several developed campgrounds on the western side of range, outside the Sawtooth Wilderness, including at Redfish, Little Redfish, Alturas, Pettit, and Stanley lakes, as well as at Iron Creek. Restrictions on fires and animals apply in some areas.

Its nearest higher peak is Fortress Mountain, 1.12 mi (1.80 km) to the west. Chiwawa Mountain is a triple divide peak, so precipitation runoff from it drains northeast to Lake Chelan via Railroad Creek; northwest into Miners Creek which is a tributary of the Suiattle River; and south into the Chiwawa River headwaters. The mountain's name is taken from the river's name, which was applied by Albert Hale Sylvester (1871-1944), a pioneer surveyor, explorer, topographer, and forest supervisor in the Cascades. Chiwawa comes from the Columbia-Moses language and means a kind of creek.

The Colchuck Glacier which lies on the northeast slopes of the peak melts into Colchuck Lake. The mountain and glacier take their name from the lake, which in Chinook jargon means "cold water". Precipitation runoff from the peak drains north into Mountaineer Creek, a tributary of Icicle Creek, or south into Ingalls Creek, all of which winds up in the Wenatchee River.
