1954 Map of McGrath B-4

About this map

Lone Mountain stands as a primary landmark in this interior Alaskan wilderness, rising above a vast network of wetlands and shifting watercourses. The landscape is defined by the braided path of the Big River, which winds northwest across the terrain, and the Middle Fork Kuskokwim River situated along the eastern edge of the quadrangle. Produced from 1953 aerial photography and field-annotated in 1954, this survey captures the region before any established roads or permanent trails were documented by the Department of the Interior. The map illustrates a complex hydrology of unnamed ponds and marshes, highlighting the intricate drainage patterns characteristic of the Yukon-Koyukuk region during the mid-20th century.
