Abstract
Unique volcanic structures, known in the literature
as “lava trees” and “tree molds”, have formed at
several sites on Mt. Etna volcano (northeastern Sicily,
Italy). They form when a fluid lava flow runs over a tree,
wraps around it and, while the wood burns off, solidifies
forming a hollow cast of the tree. The inhabitants of the
Etna area call these formations “pietre cannone” (“cannon
stones”) because of their cylindrical shape. The first
documentation of lava trees is from Hawaii, but the first
eye-witnessed accounts of their formation are, to our
knowledge, from Etna’s 1865 eruption. Although many of
the literature examples of lava trees and tree molds formed
in pahoehoe, many of those reported in this work formed in
a’a. The sites where we have found the lava tree molds are
located within the territory of the Etna Regional Park; most
occur next to walking trails and have a high potential for
geotourism.
