1956 Map of Black River B-5

About this map

The Black River meanders through a landscape of wetlands and low-lying terrain in this interior Alaska region. Much of the area is defined by the Yukon Flats, a broad floodplain characterized by a complex network of small lakes and marshes. Tchulkade Lake stands as one of the larger named water bodies within this intricate aquatic system, situated west of the main river channel. The topography is generally subtle, though Bearnose Hill provides a distinct rise in elevation to the northwest. Following the Alaska National Interest Lands Conservation Act in 1980, these lands were formally incorporated into the Yukon Flats National Wildlife Refuge. The map details the transition from the wet basin to the higher ground marked by the Refuge Boundary in the south, illustrating the vast, roadless environment of the subarctic wilderness as it was documented in the mid-1950s.
