Mount Erebus is Antarctica’s second largest volcano and has been observed to be continually active since 1972. Atop the mountain are a number of ice towers formed as a result of steam emissions from volcanic activity. Many of the ice towers constantly emit steam giving them the appearance of chimneys jutting out of the icy volcano’s frozen sides. In addition to these chimney-like pillars the volcanic mountain is home to a variety of ice caves, formed naturally in a number of ways, all resulting in glowing blue, eerily cavernous subterranean chambers. --
