An environmentally-conscious reconstruction of footage from a June 2008 trip to Alaska shows America's "Last Frontier" pulsating with life and energy - despite being threatened by man's intrusion - as rain falls on the Mendenhall Glacier, a waterfall cascades down a jagged mountain and tiny chunks of ice spin around in the ocean. The looping footage is a playful visual nod to the fact that glaciers have the ability to either advance (move forward) or retreat (move backwards) and the complex, hand-edited soundtrack contains audible traces of (unseen) aquatic life.
