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.
