Idaho's volcanic heart
The Magic Valley is geology you can drive through. The Snake River Plain that defines its northern edge is a 60-mile-wide track of flood basalts, calderas, and lava tubes left by the Yellowstone hotspot. Craters of the Moon National Monument sits at the eastern end of this surreal landscape, with cinder cones and pressure ridges cutting between sage flats. South of the Snake, the South Hills and Albion Range offer a quick climb out of the desert into pine and aspen.
