1954 Map of Ophir A-1

USGS Topo · Published 1958

About this map

The Innoko River winds through the heart of this interior Alaska territory, where 1950s mapping reveals a landscape shaped by remote industrial activity and water management. Evidence of the region's mining heritage is prominent along the southern drainages, specifically at the Placer Mine near Yankee Creek and Independence Creek. A notable Ditch system runs parallel to the watercourses, indicating the extensive hydraulic infrastructure required for placer operations in this permafrost environment.
