Indian Heaven is a polygenetic volcanic field in Washington, United States. It is located midway between Mount St. Helens and Mount Adams, and dates from the and Holocene. The field trends north to south and is dominated by seven small shield volcanoes that may have each erupted only once. Those shields are topped by small spatter and cinder cones. The northernmost peak in the field is Sawtooth Mountain and the southernmost is Red Mountain. The highest point is Lemei Rock at 5,925 feet (1,806 m). Its last volcanic activity produced a large cinder cone and a voluminous lava and scoria flows about 8,200 years ago.
About 60 eruptive centers lie on the 19-mile (30 km) long, N10°E-trending, Indian Heaven fissure zone. The 230-square-mile (600 km2) field has a volume of about 20 cubic miles (100 km3) and forms the western part of a 770-square-mile (2,000 km2) Quaternary basalt field in the southern Washington Cascades, including the King Mountain fissure zone along which Mount Adams was built.
Popular fishing and hiking destinations in the volcanic field include the Indian Heaven Wilderness, which is rather popular for the high mountain meadows among its scattered 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 spectacular views of four nearby volcanoes: Mount Adams, Mount Hood, Mount St. Helens, and Mount Rainier. It is also known to hikers for an intense population of mosquitoes throughout the summer. Other major trails in the area are Indian Heaven Trail and the Cultus Creek Trail, which climbs up the east side of Bird Mountain; and Lemei Trail which traverses up the east side of Lemei Rock and passes by Lake Wapiki.
