2016 Map of Wiseman B-4 SW

About this map

The John River marks the southwestern extent of this remote Brooks Range landscape, flowing through a region dominated by steep vertical relief and high-elevation drainages. This 2016 survey illustrates the hydrological network of the Yukon-Koyukuk region, where several significant tributaries including Crevice Cr, Bullrun Cr, and Timber Cr carve through the mountainous terrain. The map is organized by the Public Land Survey System, showing the boundaries between t29n r20w, t29n r19w, t28n r20w, and t28n r19w. The contour lines reveal a deeply dissected topography, characteristic of the northern Alaskan interior before these waters reach larger valley floors. The absence of roads or permanent structures on this sheet underscores the wilderness character of the area, making it a critical reference for understanding the natural drainage patterns of the John River basin.
