About this map

Little Tonzona River and the Big Salmon Fork dominate this interior landscape within the Yukon-Koyukuk Census Area. The region is defined by an intricate network of waterways, where the meandering course of the Little Tonzona River cuts across the northern half of the quadrangle while the Big Salmon Fork and its tributaries, such as Deepbank Creek and the curiously named No Creek, weave through the southern reaches. This topographic record by the U.S. Geological Survey illustrates a wilderness largely undisturbed by modern infrastructure, where the natural drainage patterns of the South Fork Jones Creek dictate the character of the terrain. The absence of roads or permanent settlements highlights the isolated, river-driven geography of this Alaskan interior.
