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?

Thermal Imaging Time Lapse of Dragonfly Falls
This was a final project for JRN 480 Documentary Filmmaking at the University of Alaska Fairbanks. While not taking radar transects of the ice I shot everything by cellphone, GoPro, and a Panasonic AG-HMC40. On the science behind waterfall ice: Waterfall ice is a form of ice that has been rarely studied scientifically.
