Yukon-Koyukuk Census Area

The Yukon-Koyukuk Census Area spans 147,842 square miles of Alaskan territory, making it the largest county-equivalent region in the United States.

Native Alaskan groups, particularly the Athabaskan people, established settlements along the Yukon and Koyukuk rivers before the arrival of European explorers.

The region maintains strong indigenous traditions through subsistence activities like hunting, fishing, and gathering, which form the foundation of local communities.

Transportation within Yukon-Koyukuk relies primarily on river systems and limited road networks, with seasonal variations affecting accessibility to different areas.

The census area contains portions of the Arctic National Wildlife Refuge and Gates of the Arctic National Park, representing 20 percent of Alaska's total land mass.
