1990 Map of Beaver D-2

About this map

Yukon Flats dominate this landscape, showing a complex network of seasonal water and low-lying terrain within the National Wildlife Refuge. The map identifies rare geological formations known as Pingos, which are ice-cored mounds common in permafrost regions. Human presence is marked by isolated outposts like Fiftysix Mile Cabin and Fortysix Mile Cabin, connected by a long Winter Trail that cuts north-to-south across the Fairbanks Meridian. These cabins and named water bodies such as the Hadweenzic River and Fortymile Lake reflect the subsistence and transit patterns of the Alaskan interior during the late 20th century. The intricate drainage system, including Fortytwo Mile Creek and Forty and One-half Mile Creek, underscores the reliance on specific landmarks for navigation in a region without a permanent road network.
