Atacama penitentes, Chile: "The snow undergoes a process of sublimation – when ice changes directly to gas without changing to water first. The sublimation causes pits in snow that hollow out to deeper caverns. When ice sublimates in the caverns, it turns to mist – and makes the climate in the cavern wet enough for liquid to form." *Click for more, including a video.
