B5 is the smallest sheep unit in the state but has great access and has produced great rams over the years. The western and northern parts of the unit consist of the North Dakota badlands, which means rough and rugged terrain. There are plenty of buttes and draws, especially along the Little Missouri River, that hold bighorn sheep.

Rams in this unit have generally been taken from the northern portions of this unit. Some areas are more rugged and remote than others. Be sure to check out the harvest reports for a good starting point in search of a good mature ram.
