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

For years, researchers like Haub School research scientist Sam Dwinnell have been using 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 to film the expedition and bring viewers along for the ride.

Laurels showing the film was accepted into the Banff, Wild & Scenic, and No Man's Land film festivals



We need some help to take “Deer 139” on the road this winter. 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.
