The forested slope in the foreground is part of the Big Lava Bed, a lava flow of 0.9 cubic kilometers in volume that emanated from the cinder cone in the background about 8,200 years ago. The lava flow flowed over 13 km from its starting point and is the youngest object of the Indian Heaven volcanic field . |

The Big Lava Bed is a lava field in the Gifford Pinchot National Forest , located in the southwest of the US state Washington and originates from a 500 ft (152 m) deep volcanic crater in the northern center of the lava field. The Big Lava Bed is the youngest property in the Indian Heaven volcanic field . The lava flow of 0.9 cubic kilometers in volume was ejected from a cinder cone about 8,200 years ago. The lava flow flowed over 13 kilometers from its place of origin. Coastal pines , alders and other pioneer plants began to grow and formed light stands in the midst of high rock pillars, caves and bizarre lava structures. Access to the interior of the lava field is difficult because there are no roads or paths leading to it or over it. Explorers are encouraged to choose their routes carefully. Compasses are not reliable everywhere, because local magnetic influences impair the reliability within the huge formation.
