Who manages the land in Unit 21C?
USGS PAD-US maps 93.6% of Unit 21C as public or tribal land. By manager:
| Manager | Acres | Share of the unit |
|---|---|---|
| Bureau of Land Management | 1,235,720 | 52.8% |
| State of Alaska | 810,394 | 34.6% |
| National wildlife refuge (FWS) | 145,548 | 6.2% |
| Not in PAD-US | 150,606 | 6.4% |
Named areas inside 21C: BLM Central Yukon Field Office (1,235,832 acres, 52.8%), State Patented (765,348 acres, 32.7%), Koyukuk National Wildlife Refuge (145,153 acres, 6.2%) and State Tentatively Approved (46,005 acres, 2%).

Federal law sets what each kind of land allows. A national preserve in Alaska is run like a national park except that sport hunting, subsistence hunting and trapping are allowed (16 U.S.C. 3201); national park and monument land is closed to sport hunting. On federal public land, rural Alaska residents can also hunt under federal subsistence rules, and the Federal Subsistence Board can close federal land to other hunters for a species. Land PAD-US does not map is mostly private, including Alaska Native corporation land, and needs the owner's permission.
What communities and roads are in Unit 21C?
The Census Bureau lists no community inside 21C. No state or federal highway crosses it, so hunters reach it by plane, boat, snowmachine or on foot.

Do nonresidents need a guide in Alaska?
For three species, yes. ADF&G's 2026-2027 drawing supplement: "Nonresidents who are citizens of the United States are required to be personally accompanied in the field by an Alaska-licensed guide OR an Alaska resident relative 19 years of age or older within the second-degree of kindred when hunting brown/grizzly bear, Dall sheep, or mountain goat." Nonresidents who are not U.S. citizens need a licensed guide for those and for every other big game species, by ADF&G's guide requirements. Moose, caribou, black bear, bison, muskox, elk and deer need no guide for a nonresident U.S. citizen.
