Pronghorn Hunting in Unit 410

Where to Find Pronghorn in Unit 410

Pronghorn in Unit 410 inhabit the prairie breaks and sage flats of the Missouri Breaks region near Winnett.

Sage Flats and Prairie Benches

The flat to rolling sage-covered prairie benches above the Missouri River Breaks hold the highest pronghorn density. Herds are visible across the open landscape. Concentrate on areas with good sage browse and nearby water sources — stock tanks and prairie reservoirs on both BLM and CMR Refuge land attract pronghorn herds.
