1971 Map of Wiseman D-2

About this map

The North Fork Koyukuk River carves a central path through this section of the Brooks Range, recorded just as the Gates of the Arctic was emerging as a federally recognized wilderness area. The 1970s landscape is defined by massive peaks and high-altitude passes, including the imposing Mount Doonerak and the sharp Frigid Crags. Unlike the developed areas of the lower 48, human presence here is limited to a single Cabin along Ernie Creek, highlighting the extreme isolation of this arctic environment. Topographic details illustrate the drainage patterns of glacial and snowmelt sources like Marshall Lake and Bombardment Creek. This survey captures the region's character as a frontier of scientific study and wilderness preservation, marking the North Slope Borough Boundary and the Fairbanks Meridian across a terrain of high ridges like Boreal Mountain and Wien Mountain.
