The Spatter Cones are no classic vents. They were formed when hot chunks of lava were thrown a short distance into the air before falling back to earth at the edge of a central vent. The still molten lumps landed on top of each other, cooled down and formed a kind of mini volcano.

The "Indian Tunnel" is the largest and longest of the lava tubes along the Caves Trail that can be accessed. To do so, you need to obtain a free permit at the Visitor Center. You will climb over rocks that can be slippery in places, but it is a unique small adventure. On the ceiling of the tube you can see lava stalactites formed as the river of lava pulled away from the ceiling, and molten material began to drip from the hot ceiling. The exit is about 800 feet further north.

This short, approx. 1 km long circular route gives a good insight into the different life forms in this lava landscape. Even if it gives the impression that no life is possible here, some plants that have adapted have grown. In spring, after the snow has melted, wild flowers even bloom occasionally.
