1970 Map of Bettles D-6

About this map

Alatna Hills dominate the central landscape of this interior Alaska region, marking a significant topographic rise between major drainages. The area is defined by its complex hydrological network, where the West Fork Henshaw Creek meanders through the eastern lowlands, mirrored by the drainage of Rockybottom Creek to the northwest. This 1970 aerial survey, later published by the Geological Survey, reveals a wilderness largely devoid of permanent human infrastructure, characterized instead by the predetermined but unsurveyed land lines established by the Bureau of Land Management. The map focuses on the elevation and drainage patterns of the Koyukuk region before any modern industrial or transport development altered the character of these remote hills.
