From the National Park Service website:
The Craters of the Moon is a vast area of lava flows and scattered islands of cinder cones. The lava landscape is the result of periodic eruptions along the Great Rift, a chain of cracks and fissures nearly 52 miles long running north to south through the monument. A series of Hawaiian-style eruptions over the past 15,000 years have produced lava tubes, cinder cones, and a variety of lava flows that are accessible from the 7 mile loop road.
Craters of the Moon is one of the most accessible and awe-inspiring places in the country to learn about volcanic geology. It is the largest and most complex post-Ice Age basaltic lava field in the continental United States. In the past 15,000 years eight major eruptive periods formed the Craters of the Moon Lava Field. During this time the Craters of the Moon Lava Field grew to cover 618 square miles. In contrast, most of the other lava fields on the Eastern Snake River Plain (including the Kings Bowl and Wapi Lava Fields) represent single eruptions. The Craters of the Moon Lava Field consists of up to 60 lava flows and 25 cones.
