Unit 3B1 offers several prime hunting areas for whitetail deer, particularly to the north and south of the Missouri River, where the terrain can be quite challenging. The creek bottoms near the river are mostly covered in dense cottonwood groves, with scattered ash and willow trees. While you may come across some patches of evergreens, cottonwoods dominate the landscape in this unit. The Missouri River runs from west to east through the unit, eventually flowing into Lake Sakakawea at the eastern boundary.
