The film series builds toward the print release of C&K‘s June 2013 issue, in which a feature story chronicles the story of a group of college friends paddling the Colorado River from its headwaters down in back-to-back, historic high- and low-water years. Powell to Powell documents the crew’s 2012 expedition starting from the source of the Colorado River in Rocky Mountain National Park, navigating endless diversions and dams, to its “terminus” at the Glen Canyon Dam.

Punctuated by a series of interviews along the way with water experts of all kinds, ranging from farmers, ranchers, politicians and environmental nonprofits, the series seeks to spread understanding of the ecological issues and threats facing a used and abused river drainage at risk. This fourth episode explores the wilderness stretches of the Colorado above Lake Powell and the small steps that users can take to demand protection for such a high-value resource. The next and final episode sees the crew finish its downriver journey from packrafts to whitewater boats to sea kayaks to canyon rafting, ending with a final push across Lake Powell in a unique solar-powered raft.
