1954 Map of Iditarod D-6

About this map

The Netletna River drainage dominates this mid-century topographic study, which was compiled using aerial photographs from 1953. The landscape is defined by extensive wetlands and marshy lowlands surrounding the winding courses of the Big Yetna River and Little Yetna River in the eastern portion of the quadrangle. Published in 1962, the map reflects a period when this part of the Alaska interior remained largely wild, with the Bureau of Land Management predetermining land lines for future surveying. The intricate network of smaller tributaries and the vast expanse of low-relief swamps suggest a terrain shaped by seasonal water movement, offering an essential reference for understanding the natural drainage patterns of the region before any modern human encroachment.
