Found on the edge of the Devil Mountain Maar, this piece of petrified wood was ejected from the sedimentary rock lying beneath the volcano 17,500 years ago. A maar is formed by a phreatomagmatic eruption caused by the explosive interaction of magma and water (permafrost in this case). The Devil Mountain Maar is considered to be the largest in the world.
Maximum width is 13.5 cm.
