The youngest eruption of the Indian Heaven volcanic field, midway between Mount St. Helens and Mount Adams, produced a large cinder cone and a voluminous lava flow about 8200 years ago. The source of the flow is the cinder cone at the right, with Mt. Hood visible in the background. The Big Lava Bed flow, which forms the smooth slope in the foreground, banked against higher slopes to the north and traveled 13 km south to within 8 km of the Columbia River.

The forested slope in the foreground is part of the Big Lava Bed, a 0.9 cu km lava flow erupted from the cinder cone in the background about 8200 years ago. The lava flow traveled 13 km from the source crater and is the youngest feature of the Indian Heaven volcanic field.

Red Mountain (1513 m), seen here from the NE, is the southernmost of a N-S line of small shield volcanoes capped by pyroclastic cones that form the Pleistocene-to-Holocene Indian Heaven volcanic field in the southern Cascades of Washington. The field covers 600 sq km.

Berry Mountain on the left and Gifford Peak and East Crater on the right are small Pleistocene shield volcanoes capped by pyroclastic cones. They are part of the Pleistocene-to-Holocene Indian Heaven volcanic field in the southern Cascade Range of Washington, which lies between Mount St. Helens and Mount Adams.

Lemei Rock (1813 m), seen from the Forlorn Lakes to the SE, forms the high point of the Indian Heaven volcanic field midway between Mount St. Helens and Mount Adams. The 600 sq km field consists of overlapping small shield volcanoes with pyroclastic cones and lava flows. The field was active from about 730,000 to about 8200 years ago, and contains some volcanic features that originated beneath a glacial icecap.

Lavas of the Big Lava Bed flow, erupted about 8200 years ago from the cinder cone in the background, dammed local drainages, forming Goose Lake. The Big Lava Bed flow is the most recent eruption of the Indian Heaven volcanic field, which lies between Mount St. Helens and Mount Adams.
