About this map

Craters of the Moon National Preserve dominates this volcanic landscape along the border of Butte and Blaine counties. The survey reveals a complex network of geological formations, including the sprawling Sawtooth Flow and the distinct Fissure Butte Flows. These features are tied to the Great Rift, a massive volcanic fissure system that has shaped the eastern Snake River Plain over millennia.

Notable landmarks such as the Bridge of the Moon and Vermilion Chasm punctuate the basaltic terrain, while several distinct volcanic cones like Sheep Trail Butte and Split Butte rise above the surrounding lava fields. The map also identifies specific flow patterns like the Sentinel West Flow and the Little Prairie Aa Flow, providing a detailed record of the region's unique volcanic activity and naming the specific geographic landmarks that define this protected wilderness area.
