2016 Map of Healy D-4 NE

About this map

Jumbo Dome serves as the dominant landmark in this interior Alaskan landscape, anchoring a terrain defined by a dense network of high-elevation drainages. Flowing from the south, Healy Creek and its many tributaries, including Coal Creek and Cripple Creek, create a complex hydrographic pattern typical of the coal-bearing formations found in this part of the Denali region. To the north, the Totatlanika River and Ptarmigan Creek drain away from the prominent slopes surrounding Ptarmigan Lake. The abundance of creek names like Lignite Creek and Sanderson Creek underscores the region's geological significance and the historical interest in its mineral-rich valleys. This 2016 survey provides a precise view of the watersheds and topographic relief before they transition into the broader Tanana Valley to the north.
