1954 Map of Melozitna B-4

About this map

The Melozitna River winds through this interior Alaskan wilderness, exhibiting a complex series of oxbow lakes and abandoned channels that indicate a highly active fluvial landscape. Surveyed in the early 1950s using photogrammetric methods from 1952 aerial photography, the map reveals a terrain dominated by expansive wetlands and intricate waterways. In the northern portion of the quadrangle, the Dulbi River cuts across the landscape, while the southern reaches are marked by the presence of Big Creek. This document captures the region during a period of systematic federal mapping by the Geological Survey, providing a record of the Kateel River Meridian and the Base Line as predetermined by the Bureau of Land Management before extensive surface navigation or roads reached this portion of the Yukon-Koyukuk region.
