2021 Map of Big Delta C-4 NE

About this map

The Salcha River basin dominates this interior landscape within the Fairbanks North Star Borough, where the river's meandering course creates a broad, sediment-filled valley floor. This 2021 survey reveals a complex hydrological network defined by steep-walled tributaries like Caribou Cr and the curiously named No Grub Cr. The terrain is characterized by high, rhythmic contour lines that indicate significant elevation changes between the river basin and the surrounding uplands. Other prominent drainages including Bullfrog Cr, Pasco Cr, and Butte Cr feed into the primary river system, illustrating the natural drainage patterns of this Alaskan wilderness. In the northern reaches, Bonanza Cr cuts through the high ground, reflecting the typical landscape architecture of the region where water systems are the primary force shaping the topography.
