The Erebus Rock is a piece of anorthoclase phonolite, an igneous rock, that was ejected from [[Mount Erebus]] on [[Ross Island]] in [[Antarctica]]. The rock contains tiny fissures with dull gray-green prismatic euhedral crystals inside. These crystals formed as a result of the hot lava cooling rapidly in the subfreezing Antarctic temperatures. The Erebus Rock is considered a sacred relic and is only permitted to be touched under certain conditions (and even then, under close supervision). | The Erebus Rock is a piece of anorthoclase phonolite, an igneous rock, that was ejected from [[Mount Erebus]] on [[Ross Island]] in [[Antarctica]].
