A pingo is a geological feature found in arctic and sub-arctic regions composed of a large mound of ice which has become covered with earth. The term comes from an Inuit word meaning "small hill" and they are found in northern Canada, Siberia, Greenland and other places in the Arctic.
Sometimes large pingos will have craters, resembling that of a volcano, on top; formed by cycles of the ice melting and re-freezing with the seasons. These craters might contain small lakes, weather permitting.
