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.
Introduction:
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.---
