Craters of the Moon, the largest lava field of the Snake River Plain, covers about 1600 sq km with more than 60 mappable lava flows erupted from eight fissure systems. About 25 cinder cones up to 250-m high formed primarily along a 45-km-long segment of the Great Rift, the principal 2-8 km wide fissure system that trends NW-SE through Craters of the Moon National Monument. Craters of the Moon lies at the NW part of the eastern Snake River Plain, and the northern part of the field laps up against the White Knob and Pioneer Mountains. The lava field was formed during eight eruptive episodes between about 15,000 and 2000 years ago separated by quiescent periods up to about 3000 years in duration. This contrasts with other Snake River Plain lava fields, which were formed during single eruptive episodes of relatively short duration. A complex assemblage of basaltic volcanic features is found at Craters of the Moon, and cinder cones are common, in contrast to other Snake River Plain lava fields.
