1986 Map of Survey Pass A-1

USGS Topo · Published 1986

About this map

Iniakuk Lake occupies the central valley of this remote subarctic landscape, bordered to the north by Mount Hal Waugh. This 1986 provisional survey, based on photography from the early 1970s, documents a wilderness defined by its complex drainage systems and the Kateel River Meridian Boundary running along its eastern edge. The Alatna River and Iniakuk River dominate the lowlands, creating intricate meanders and marshy basins such as those near the Malamute Fork. To the south, the Alatna Hills rise above the river plains, while numerous smaller waterways like Tobuk Creek and Cummings Creek drain the surrounding heights. The lack of any roads or trails on the sheet emphasizes the purely topographical nature of the region during this era, serving as a primary record for those studying the hydrologic patterns and landforms of the Yukon-Koyukuk region.
