2016 Map of Hughes B-4 SE

About this map

Hogatza Flats dominates this portion of the Yukon-Koyukuk region, revealing an intricate landscape of interior Alaskan wetlands and wandering watercourses. The 2016 survey documents the shifting hydrography of the Hogatza River and Tallinkho Cr as they thread through a dense network of unnamed ponds and marshes. To the east, the terrain rises toward the base of the ridges surrounding Twin Lakes, contrasting the low-lying basin to the west. Central to this map is Lake Kyikhgyit, a prominent water body in a region defined by its seasonal drainage patterns. The southern reaches are marked by the flow of Koskatantna Cr, illustrating the complex watershed typical of the Koyukuk basin where water levels and channels are in constant transition.
