1956 Map of Tanana D-1

About this map

The Yukon River sweeps through the southeastern corner of this Alaskan interior landscape, a vital corridor for travel and survival long before modern infrastructure arrived. Revisions from 1975 capture a significant moment in the state's industrial history, showing the Trans-Alaska Pipeline (Under Construction) as it began to cut through the wilderness near the Ray River. The rugged topography is defined by major drainages like the Big Salt River and the meandering Little Salt Creek, which together shape the region's complex watershed.
