1985 Map of Ambler River A-3

USGS Topo · Published 1985

About this map

The Ambler River cuts a wide path through this Arctic landscape, creating the expansive Ambler Lowland where surface water gathers into distinctive features like Lake Anirak and Lake Talhak. This 1985 survey, based on aerial photography from the mid-1970s, reveals a terrain defined by high peaks and an intricate drainage network. To the south and east, the elevation rises sharply into a series of named summits including Bismark Mountain, Eightmile Mountain, and the massive Shungnak Mountain. The hydrology is remarkably complex, with numerous tributaries such as Woodchopper Creek, Kalurivik Creek, and Cosmos Creek feeding the main river system. The proximity of Cosmos Mountain and Iron Mountain suggests a geologically significant area where the flat river basin meets the southern reaches of the Brooks Range foothills.
