1950 Map of Valdez A-3

About this map

The Copper River and Northwestern Railroad corridor defines this mid-century topographic record, tracing the eastern bank of the massive Copper River delta. Based on aerial photography from 1950, the sheet captures a landscape dominated by the movement of ice and water, where the Schwan Glacier feeds into the broad, braided valley of the Tasnuna River. The intricate river systems, including the Tiekel River and numerous tributaries like Thunder Creek and Cleave Creek, illustrate the complex drainage patterns found south of the central Chugach Mountains.
