1951 Map of Big Delta A-6

USGS Topo · Published 1951

About this map

The Little Delta River dominates this 1951 survey of the Alaska Interior, its braided channels carving a complex path through the terrain. This map, based on aerial photography from August 1949, captures the wilderness as it was before modern infrastructure altered the landscape. A single Winter Trail provides the only named overland passage, reflecting the seasonal movement patterns required by the high-latitude environment. The surveying point VABM Delta 1524 stands as a primary landmark in a region defined by its natural drainage patterns rather than permanent settlements. Researchers can study the unchecked elevations and intricate contouring that illustrate the drainage basin of the river system during the early post-war era of Alaskan mapping.
