About this map

The S Fork Koyukuk River winds through this northern interior landscape, serving as the central hydrological artery for a series of named tributaries and upland drainages. Elevations rise sharply from the river valley toward features like Dennys Gulch, with the terrain characterized by complex contouring and remote glacial relics. Small bodies of water such as Twin Lakes and S Fork Lake are prominent in the northern and western sections of the quadrangle, respectively.

The drainage network is particularly dense, including Woodland Echo Cr, Sawlog Cr, and Crooked Cr. This 2017 survey reflects the unchanged, roadless nature of the region, where the landscape is defined by its watercourses rather than human infrastructure. The map provides a high-resolution look at the intricate relief of the Yukon-Koyukuk interior, marking the boundaries of several townships including t31n r7w and t30n r8w.
