Unit 3A1 offers a greater variety of terrain than many other GMAs in northern North Dakota. In addition to the usual rolling hills, rocky soils, creek bottoms, and small lakes, this unit also includes steep inclines and significant elevation changes. Notably, areas east of Tioga and along the White Earth River feature hillsides where the elevation can drop or rise by 300 feet over just a few hundred yards. The unit is home to healthy deer populations, with whitetail being more abundant, though there are also excellent opportunities to hunt mule deer.
