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. Ice waterfalls are an ephemeral part of our landscape that often do not leave a trace of their existence when the winter ends. Even at temperatures as low as -40 or -30C, water can still flow within or under ice in streams and over waterfalls. How? Because water generates heat when it freezes, this heat warms the surrounding ice and creates a protective warm pathway for water to continue flow despite cold temperatures. In this way, it is an analogy for water flowing through conduits in cold glacier ice - a process that may be more prominent than we thought possible.
Waterfall Ice also supports an active climbing community - one with different challenges and dangers than rock climbing. Under some conditions, one stroke of an ice tool can cause a chunk of ice that is large enough to kill someone to fall, the same piece of ice may have been perfectly safe a few days earlier.
