Dark lava flows extend from the 6-km-long Kings Bowl Rift SE of Craters of the Moon. These flows were erupted at the same time as the much more massive Wapi lava field flows immediately to the south that covered about 300 km², forming a broad, low shield volcano about 2250 years ago. The light-colored area overlying the lava flows at the lower center of the photo is an ash deposit produced by explosions from Kings Bowl crater.
