Nature & Science
The awesome effects of volcanism are evident throughout Craters of the Moon National Monument and Preserve. Over the past 15,000 years, lava eruptions created a rugged landscape that provides habitat for a surprising diversity of plants and animals in a high desert ecosystem.
Preservation of the unique geological and biological features found here is the overriding purpose of the Monument. To that end, basic and applied scientific research, resource inventories, and monitoring of resource conditions play important roles in the identification, characterization, and interpretation of the Monument’s resources.

Watch out for bombs! Before they cooled, volcanic bombs were hot globs of lava that were hurled from volcanoes along the Great Rift. They form a variety of interesting shapes described as "breadcrust", "spindle" and "ribbons" by geologists.
