Waterfalls that freeze in the winter provide a wonderful local learning opportunity for studying thermal and crystal evolution processes in ice. We use embedded temperature sensors, thermal imaging cameras, time lapse cameras, weather stations, and ice core sampling to study the ice at Dragonfly Falls, Alaska.
How does latent heat help water flow at -40C?
How do ice crystals grow inside an icicle?
