A film detailing the 85-mile-long migration path of a Wyoming mule deer doe and the University of Wyoming biologist who has studied her will be screened in Cody next week.

The film, “Deer 139,” follows UW research scientist Samantha Dwinnell and two friends as they hike, packraft and ski the migration route of a GPS-collared mule deer in search of deeper understanding about the connection these animals have to the landscapes where they live.

The documentary will be screened at Big Horn Cinemas on Monday, at 4:30 p.m. and 7 p.m. Both screenings are free and open to the public.

A question-and-answer session with Dwinnell and Anya Tyson, a naturalist and citizen scientist project manager based in Montana, will follow the screenings. In addition to Dwinnell and Tyson, the film also stars Tennessee Watson, a reporter for Wyoming Public Media, and Deer 139 herself.

The 53-minute-long film follows the three adventurers as they travel the deer’s migration path on foot from her winter habitat in the Green River Basin, through the foothills of the Wyoming Range, over a high mountain pass to the Greys River, to summer habitat in the Salt River Range.

In between twisted ankles, David Attenborough impressions and mountaintop dance parties, the three women experience the challenges to long-distance migration in the modern world and gain new perspective about the value of interconnected landscapes. By considering the story of one specific animal, the doe known as Deer 139, they learn to see Wyoming’s backyard as not only a source of natural resources and a recreational playground, but also a place where wild animals have honed their existence over millennia to perfectly synchronize with a rugged and unforgiving landscape.

The Monteith Shop and the Ruckelshaus Institute, both within UW’s Haub School of Environment and Natural Resources, produced the film as part of its mission to share new scientific understanding with a broad audience.

Dwinnell, along with Associate Professor Kevin Monteith and Communications Coordinator Emilene Ostlind, all in the UW Haub School of Environment and Natural Resources, produced the documentary, while filmmakers Morgan Heim and Jayme Dittmar directed it.

During Monday’s screening in Cody, a raffle for sponsor prizes also will be held, with proceeds supporting the film and wildlife conservation. The Greater Yellowstone Coalition is sponsoring the event.

The film will also be screened in Etna, Lander and Big Horn. To view the film trailer or for more information, visit www.deer139film.org.
