2019 Map of Medfra A-1 NW
USGS Topo · Published 2019About this map
Dennis Lake sits at the heart of this sub-arctic terrain in the Yukon-Koyukuk Census Area, surrounded by a complex system of waterways and elevation gains. The drainage pattern of the landscape is defined by the Slow Fork at the northern edge and the winding courses of Grayling Creek and Dennis Creek to the south. This 2019 survey, based on SPOT imagery and National Hydrography Dataset records, illustrates the remote interior of Alaska before significant human infrastructure reached this specific section of the Unorganized Borough. The map detail highlights the intricate contours of the land across the t26s r28e and t27s r29e townships, where the natural water network remains the primary defining feature of the geography.
