# Sawtooth Mountain

Sawtooth Mountain is a shield volcano, and part of the polygenetic Indian Heaven Volcanic Field in Washington, United States. It is located midway between Mount St. Helens and Mount Adams, and dates from the Pleistocene and Holocene. Sawtooth Mountain is the third highest point at 5,354 feet (1,632 m)in this region. The mountain forms a series of welded volcanic rock spires, an eroded remnant of an ancient shield volcano. Sawtooth Mountain is the third highest point in the Indian Heaven Wilderness Area. While Sawtooth Mountain is not the highest, its craggy appearance makes it one of the most namesake peaks in the Indian Heaven Volcanic Field.

## Geographical setting

Sawtooth Mountain is the third highest peak the Indian Heaven Wilderness in Washington. On clear days hikers can see views of four nearby volcanoes: Mount Adams, Mount Hood, Mount St. Helens, and Mount Rainier from the Sawtooth Mountain Trail, which skirts the subalpine upper west side of Sawtooth Mountain. The shield volcano is noted as a series of eroded, volcanic spires. While the mountain is free of snow and ice, snow tends to linger on the summit well into July.

## Geology

Sawtooth Mountain is one of the many shield volcanoes topped by cinder cones and spatter cones that make up the Indian Heaven Volcanic Field. About 60 eruptive centers lie on the 19-mile (30 km) long, N10°E-trending, Indian Heaven fissure zone. The 230 square miles (600 km$^2$) field has a volume of about 20 cubic miles (100 km$^3$) and forms the western part of a 770-square-mile (2,000 km$^2$) Quaternary basalt field in the southern Washington Cascades, including the King Mountain fissure zone along which Mount Adams was built.

## Climbing and recreation

Fishing and hiking destinations in the volcanic field around Sawtooth Mountain include the Indian Heaven Wilderness, which is popular for the high mountain meadows among its volcanic peaks. The Pacific Crest National Scenic Trail passes north/south through the volcanic field and the Indian Heaven Wilderness, which is known for its many lakes and views of four nearby volcanoes: Mount Adams, Mount Hood, Mount St. Helens, and Mount Rainier. It also hugs the densely forested east side of Sawtooth Mountain, and in conjunction with the Sawtooth Mountain Trail, can be hiked in a loop beginning at the Sawtooth Trailhead. Wood Lake is to the west of the peak, and a spur trail (Wood Lake Trail) leaves the Pacific Crest Trail for the lake. Major trails at Sawtooth Mountain are the Sawtooth Trail, which climbs up and skirts the upper west side of Sawtooth Mountain; and Wood Lake Trail, which descends west from the Pacific Crest Trail to the deep blue Wood Lake. The Pacific Crest Trail skirts the densely forested lower west side of the peak.
The Sawtooth Berry Fields is located north of Sawtooth Mountain, around Surprise Lakes and the Sawtooth Trailhead for the Pacific Crest Trail.
