2019 Map of Medfra B-4 NE

About this map

The Mystery Mountains dominate the northeastern reaches of this interior Alaskan landscape, providing a sharp contrast to the wandering drainage of the Nixon Fork below. This 2019 survey documents a wilderness where water and topography define the only visible structure. The terrain transitions from the high elevations of the Kuskokwim Mountains in the southwest toward the lower basins where Cottonwood Cr flows. Without any roads, settlements, or structures recorded, the map reflects a remote environment shaped entirely by natural features. Researchers can examine the precise contouring of these distinct mountain ranges and the hydraulic patterns of the river systems that have carved through the central Yukon-Koyukuk region.
