[[Image:Hornito.jpg|thumb|300px|Hornito forming on east rift zone of Kilauea during the Pu`u `O`o-Kupaianaha eruption.]]A '''Hornito''' is a small rootless [[spatter cone]] that forms on the surface of a basaltic lava flow (usually [[pahoehoe]]). A hornito develops when lava is forced up through an opening in the cooled surface of a flow and then accumulates around the opening. Typically, hornitos are steep sided and form conspicuous pinnacles or stacks. They are "rootless" because they are fed by [[lava]] from the underlying flow instead of from a deeper magma conduit.
