About this map

Yukon Flats National Wildlife Refuge encompasses a significant portion of this interior landscape, which was mapped by the U.S. Geological Survey using aerial photography from 1978 and 1985. The terrain is defined by its complex drainage systems, most notably the winding path of Marten Creek which traverses the central and southern reaches. This 1990 provisional edition documents the land's character before more recent environmental shifts, preserving the layout of seasonal routes like the Winter Trail in the northwest. The presence of these specific water and transit markers offers a record of the region's accessibility and environmental management during the late twentieth century, particularly within the boundaries of the established wildlife refuge.
