In our 10X10 series, we examine places that might not seem all that interesting... places like your typical frozen pond.  Sure, on the surface it's a wind-swept desert of crunchy snow and frigid temperatures, but drill a few inches down though, and you'll discover a world turned upside-down. In this episode, we give the down low on bizarre properties of water, fish that thrive in a capped-off environment, and long beards of algae clinging to the underside of a secret ecosystem few have ever explored.
