Ice cave on Mount Erebus

Ice cave


An ice cave on Mount Erebus, a volcano on Ross Island, Antarctica, takes on an ethereal blue glow from light shining through the ice. Geothermal processes such as the venting of gas and heat from the volcano's magma chamber form fumaroles and ice caves around its flanks. Mount Erebus boasts a rare lava lake.
