Novarupta Dome, an almost perfectly circular mass of rhyolite lava, was emplaced at the Novarupta vent site in the weeks to months following the explosive eruption of June 6-9, 1912. The dome is roughly 500 m across and sits in the nearly 2-km-wide vent crater. The rubbly texture is characteristic of silicic lava domes.
