1955 Map of Noatak D-4

About this map

Iyikrok Mountain dominates the northeastern corner of this sub-Arctic landscape, providing a stark topographical anchor for the surrounding water-rich lowlands. This mid-century survey reveals a complex hydrological network where the Wulik River winds westward across the tundra, joined by tributaries such as Ikalukrok Creek and Tulak Creek. The map shows a region defined by its lack of established infrastructure, featuring land lines that represent unsurveyed and unmarked locations predetermined by the Bureau of Land Management. From the high point at Mount Jarvis to the sharp elevation change at Imnak Bluff, the terrain is a mosaic of small lakes and seasonal drainages. At the southern edge, Imikruk Creek cuts through the marshy flats, illustrating the typical drainage patterns of the Noatak region during the 1950s before significant modern changes.
