This unit is found in central Alaska and features a great deal of terrain types. Most of the region can be primarily classified as boreal forest but much of the central portion of the unit is largely covered in muskegs and bogs. In these areas, water is everywhere in the form of small ponds, akes, and oxbows. Rugged mountains will be found along the northern border in the Purcell and Zane mountain ranges This unit is primarily remote with a handful of settlements being found on the Koyukuk River. Most of the hunting here will be conducted on fly in trips or by utilizing some of the many available rivers. Several species are available to be hunted here with the primary target animal being Moose.

Access options are limited for this unit but hunters will find great hunting here for their effort.

This entire area is primarily comprised of large rolling hills with timber stands and tundra in the lower elevations and large expansive tundra on the tops of ridgelines. Many creeks and rivers cover this area and make for a diverse area with plenty of room for game to hide. By utilizing the many small ridges and rolling hills hunters can find excellent vantage points and great options for movement throughout the unit. The central portions of the unit see a large expanse of boggy and muskeg areas which can make cross country travel difficult.

This area is primarily boreal forest and will see the typical makeup of birch, black spruce, willow, bramble, and tundra. Glassing conditions are great for the most part and small bumps in elevation can reveal miles and miles of terrain. Traversing the tundra can be tough walking at times. Some of the higher elevations in the region will see a good distribution of willow, alder, and black spruce. In these areas, glassing and walking conditions will be excellent. Bogs and muskeg area comprise most of the central portions of the unit. These areas will generally not see a big uptick or change in vegetation but can be tough to navigate at times.

With this unit being primarily remote most hunters will need to be flown into the unit and dropped in basecamp locations or along rivers where a float hunt can be started. Most hunters will generally be flown in from air taxi services located outside of the unit. The Koyukuk River is the primary river of use in this area but several feeder rivers flow into this that can make for excellent hunting opportunities.

For the most part, hunters will be forced to camp in the bush when hunting this area due to the remoteness. Many gravel bars can be found scattered along rivers and streams and higher ridgelines can make great base camp locations for fly in hunts.
