Craters of the Moon

Campo volcánico · United States · 2005 m

The Craters of the Moon lava field covers 1600 km2 of the Snake River Plain with lava flows erupted from NW-SE-trending fissures and cinder cones. The northern part of the lava field, seen from Big Cinder Butte with the Pioneer Mountains in the background to the north, contains many flows and cinder cones formed during the most recent eruptions about 2300 to 2100 years ago.

Resumen geológico

Craters of the Moon, the largest lava field of the Snake River Plain (SRP), covers about 1,600 km2 with more than 60 mapped 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 SRP, with White Knob and the Pioneer Mountains along the northern boundary. The lava field was formed during eight eruptive episodes between about 15,000 and 2,000 years ago separated by quiescent periods up to about 3,000 years in duration. This contrasts with other SRP lava fields, which were formed during single eruptive episodes of relatively short duration. A complex assemblage of basaltic volcanic features is present, and cinder cones are common.
