Pronghorn bound across the Seedskadee National Wildlife Refuge at sunrise in this photograph captured by Tom Koerner, the refuge manager.
Pronghorn use the refuge all year, and this group took its run for the sagebrush back in January. Today, many pronghorn in southwestern Wyoming are on the move north.
The 26,400-acre refuge runs along the Green River and was established in 1964 to offset impacts from the nearby Fontenelle Reservoir and Flaming Gorge Reservoir, located downstream. It includes about 35 miles of the Green River, is near a stronghold for Greater Sage Grouse, and takes its name from an indigenous word for the bird.
Shoshone people called the Green “river of the prairie hen,” a reference to abundant grouse. It is just beyond the southern end of the Path of the Pronghorn that extends north to Grand Teton National Park.
