1956 Map of Fort Yukon A-1

USGS Topo · Published 1959

About this map

The Yukon River carves a complex path through the interior of Alaska in the late 1950s, defined by a massive network of braided channels and shifting islands. This specific survey area is dominated by the expansive Twentytwo Mile Island, which is separated from the eastern shoreline by the Twentytwo Mile Slough. The presence of a Cabin and the Twentytwo Mile Island Village triangulation station indicates a human footprint along these active waterways, likely serving as seasonal or subsistence sites for river travel. To the east, the landscape transitions from the river's alluvial plain toward higher ground, marked only by a long Tractor Trail that provides a singular overland route through the brush. In the southwest corner, the map shows where Birch Creek nears the main river system, highlighting the intricate drainage patterns of the Yukon Flats region during this era of early aerial photogrammetry.
