Three women with backpacks hike on a highway

Deer 139

Three bold women test their endurance and wits as they brave the formidable migratory journey of a pregnant, scrawny doe

Researchers like Haub School wildlife biologist Sam Dwinnell use GPS collars to remotely track where mule deer go and how they connect with landscapes—both wild and changed by humans. Through her research, Sam has seen how these animals are endurance athletes in their migrations. Deer 139 stuck out as one of the most badass animals out there. Every year she travels 85 miles from her winter range in the sagebrush steppe outside LaBarge, Wyoming, up into and over the Wyoming Range, across raging rivers and snow fields, to an alpine cirque in the Salt River Range. As a scientist, Sam mapped this journey but the adventurer in her didn’t want to just watch from afar. To see first-hand this long, complex, and until now, largely invisible journey, Sam assembled an all-woman team of naturalists, storytellers, and endurance junkies—including crackshot documentary filmmakers Morgan Heim and Jayme Dittmar—to film the expedition and bring viewers along for the ride.

We need some help to take “Deer 139” on the road, get it into classrooms, and extend our music rights so we can eventually share the film online for free. We are trying to put this story about mule deer ecology, how wildlife use landscapes, and badass women scientists and adventurers in front of as many eyes as possible. Click here to donate.

If you donate $25 or more, we will send you a password protected link to watch the film at home. Please forward your email receipt for the donation to producer Emilene Ostlind at to receive the link.
