2016 Map of Hughes A-6 SW

About this map

The Koyukuk River meanders through the southern portion of this region, creating a complex system of oxbows and riverine features including Treat Island. This 2016 survey documents the vast elevation changes between the river valley and the rising slopes of the Zane Hills to the north. The drainage patterns are defined by several smaller tributaries, such as High Cr, which carve through the high terrain. The map provides a precise record of the Public Land Survey System grid across T8N R14E and T7N R14E, showing the intersection of waterway geography and administrative land divisions in a largely roadless interior landscape.
