Indian Heaven is a volcanic field in Washington. It is located midway between Mount St. Helens and Mount Adams, and dates from the Pleistocene and Holocene. The field trends north to south and is dominated by seven small shield volcanoes that 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.
It last produced a large cinder cone and a voluminous lava and scoria flows about 8200 years ago.
About 60 eruptive centers lie on the 30-kilometer-long, N10degreesEast-trending, Indian Heaven fissure zone. The 600 square kilometer field has a volume of about 100 cubic kilometers and forms the western part of a 2000-square-kilometer Quaternary basalt field in the southern Washington Cascades, including the King Mountain fissure zone along which Mount Adams was built.[1]
