The Nulato Hills are a series of low, rolling hills located in central Alaska. They are part of the larger Yukon-Koyukuk Census Area and are characterized by their tundra vegetation and diverse wildlife. The hills are primarily composed of sedimentary rock and are shaped by glacial activity, making them a significant geological feature in the region. These hills are situated near the Yukon River, providing a natural habitat for various species, including caribou and migratory birds. The area is also important for local Native Alaskan communities, who rely on the land for subsistence activities and cultural practices.
