1949 Map of Valdez D-7

About this map

Tazlina Lake dominates this glacial landscape, serving as a central catchment for the surrounding mountain drainages during the late 1940s. The Nelchina River flows into the northern reaches of the lake, where a complex delta system highlights the shifting hydrology of the region. Scattered cabins along the shoreline and interior waterways suggest a pattern of seasonal subsistence or remote outposts in an era before established road networks reached this interior basin. To the east, the terrain rises toward High Lake, with several significant tributaries including Mendeltna Creek, Kaina Creek, and Tokaina Creek cutting through the uplands. The survey also documents the Copper River Base Line, a critical surveying benchmark for land management in this part of the Alaskan territory.
