1966 Map of Fort Yukon A-4

USGS Topo · Published 1967

About this map

Mouth Birch Creek marks the transition between the low-lying wetlands and the rising highlands in this interior Alaskan wilderness. Surveyed in the early 1950s with minor revisions in the mid-1960s, the landscape is defined by a dense concentration of water bodies. Large, prominent features such as Twin Island Lake and Three Lakes dominate the northern flats, while the southern portion of the map rises into significant elevation points like Vabm 798 Small. The drainage pattern is led by Discovery Creek and Lower Chloya Lake, reflecting an area largely untouched by permanent settlement or road infrastructure during this era. This survey, interpreted from aerial photography by the Bureau of Land Management and the U.S. Geological Survey, provides a precise look at the hydrology of the Yukon-Koyukuk region before contemporary changes.
