Indian Heaven volcano is a volcanic field 30 km halfway between Mt St. Helens and Mount Adams volcano, Washington, USA. It contains several low overlapping basaltic shield volcanoes and more than 50 flank vents with spatter cones primarily oriented along a N-S line.
The youngest eruption occurred only about 8,200 years ago and produced the voluminous Big Lava Bed, a 0.9 km3 basaltic lava flow that traveled nearly 25 km south from its source, an unnamed cinder cone SE of Red Mountain, to within 8 km of the Columbia River.

Background
The shield volcanoes extend from Sawtooth Mountain on the north to Red Mountain on the south. Lemei Rock shield volcano forms the highest point. The volcanoes have erupted basasltic-to-andesitic lava flows which cover most of the field. There are many large lava tubes in the lava flows, some of which traveled up to 46 km.---
