The protected area's features are volcanic and represent one of the best preserved flood basalt areas in the continental United States. It is composed of encompass three major lava fields and about 400 square miles (1,036 km2) of sagebrush steppe grasslan
The three lava fields lie along the Great Rift of Idaho, with some of the best examples of open rift cracks in the world.

The Monument and Preserve contain more than 25 volcanic cones.

All plants and animals that live in and around Craters of the Moon are under great environmental stress due to constant dry winds and heat-absorbing black lavas that tend to quickly sap water from living things.
