Ice may be one of the strangest substances in the world. Full of contradictions, it is powerful enough to shatter rock but can melt in the blink of an eye; it is transparent, yet can glow with color. It can take many shapes, from a tiny snowflake to a multimillion-ton glacier to the ice fountains on far-flung moons. In this program, Dr. Gabrielle Walker searches out some of the secrets hidden deep within the ice crystal as she investigates how something so ephemeral has the power to sculpt landscapes, to preserve our past, and to inform our future.
