1970 Map of Bettles A-6

About this map

Lake Todatonten dominates the western landscape of this 1970 interior Alaska survey, a significant water body in an area defined by complex drainage and permafrost features. The map illustrates the presence of multiple Pingos and a single Pingo, which are characteristic ice-cored mounds found in arctic and subarctic environments. Navigation through this remote terrain is marked by a Winter Trail that skirts the eastern shore of the lake, indicating the seasonal nature of travel in the region during the mid-20th century. To the south and east, the drainage systems of Hogazzithethno Creek and Kodatna Creek carve through the land, showing the intricate hydrology of the Yukon-Koyukuk region before significant modern development. The map was produced using photogrammetric methods from 1970 aerial photography, capturing the land's surface as predetermined by the Bureau of Land Management.
