Its massive level rock columns were constructed inside the main volcanic vent of a stratovolcano that has since been reduced by erosion.

Blocks can be enormous and may be transported great distances from the volcanic vent.

Dacite and rhyolite lavas are usually too viscous to flow far from a volcanic vent, resulting in the formation of lava domes.

It was created by lava flowing downhill from a volcanic vent located north of the cave.

They are created when molten lava travels away from a volcanic vent and expands an old shoreline.
