This enormous unit is found in northern Alaska along the Arctic Ocean. It is generally very rare that nonresident hunters will make their way to this area with most of the hunting consisting of native residents. This area is part of the North Slope and is almost entirely tundra. This region is incredibly remote with the only access options lying in the use of bush planes. The primary species that is targeted here will be caribou although some other opportunities for additional animals do exist. **On March 30, 2022, the Federal Subsistence Board (Board) approved Temporary Wildlife Special Action WSA21-01 with modification to close some Federal public lands in Units 23 and 26A to caribou hunting by non-Federally qualified users for the 2022-2024 regulatory cycle. For caribou, the closure only applies to Noatak National Preserve (including the Nigu River portion of the Preserve in Unit 26A) and BLM-managed lands between the Noatak and Kobuk rivers in Unit 23. Collectively, this area is approximately 11,300 square miles.

Very few nonresidents will ever reach this unit with most of the hunting being done by native residents primarily during the winter months.
