Craters of the Moon National Monument (Butte County, Idaho, US)habitat desertnotes These small, steep-sided cones form where molten lava is ejected only a short distance from a vent. Usually, they develop during the final stage of an eruption, after much of the initial pressure has been dissipated. These spatter cones, formed about 2,100 years ago, are aligned along a fissure extending south from the Big Craters area. The fissure was the source of the 'Blue Dragon' lava flow.keywords: geology, earth science, Holocene, Quaternary, Cenozoic, eruption, volcano, volcanism
