Icecano

Icecanos were a type of volcano that was capable of erupting with ice instead of the traditional lava.

Spiridon had some icecanoes, due to the fact that the planet's was made of molten ice. The Daleks used the frozen temperatures to store a hibernating army of Daleks. However, this proved to be their downfall when the Third Doctor with the help of a squad of Thals, flooded the hibernation chamber and the rest of the Dalek entire base with the volcano.
