1990 Map of Ambler River C-2

About this map

The Ambler River winds through this northern Alaskan landscape, serving as a central drainage for the steep slopes within the Gates of the Arctic National Park Wilderness. Compiled from aerial photography taken in the late 1970s and early 1980s, the map illustrates a complex network of alpine watercourses including the Imelyak River and the high-elevation headwaters of Kavachurak Creek. To the west, the boundary of the Noatak National Preserve Wilderness meets the park, highlighting a protected corridor where no roads or trails were recorded. The topography is defined by sharp contour lines and numerous unnamed peaks, showcasing the drainage patterns of Tumukuchiak Creek as it feeds into the broader river valley. This provisional edition provides a detailed look at the hydrology and land management boundaries of the Northwest Arctic Borough before the turn of the millennium.
