1986 Map of Hughes D-1

About this map

The Alatna River snakes through the western portion of this terrain, marking a distinct corridor against the prominent Alatna Hills that dominate the central and eastern landscape. Several drainages, including Helpmejack Creek in the northwest and Rockybottom Creek to the north, define the watershed patterns of this interior region. The lack of roads or established trails on this 1980s provisional edition emphasizes the isolation of the area, where the Kateel River Meridian Boundary provides one of the few formal survey markers across the topography. Smaller waterways like Sinyalak Creek and Chebanika Creek carve through the southern slopes, illustrating the complex drainage network feeding into the larger river systems of the Yukon-Koyukuk region.
