2020 Map of Black B-1 SE

About this map

The Black River dominates this landscape within the Kusilvak Census Area, winding in wide meanders across a terrain defined by complex wetland systems and small, scattered ponds. This U.S. Geological Survey topographic study captures the hydrological character of the region as it appeared in 2020, illustrating the shifting path of the river through various townships including T26n R86w and T25n R85w. The map provides a precise look at the drainage patterns and low-elevation relief that characterize this part of the Alaskan interior, where the water's influence on the land is the primary geographic feature. For researchers and those interested in the remote hydrologic systems of the North, the detailed contours and wetland data show the subtle shifts in the river's course over time.
