1958 Map of Kenai D-7

About this map

Blockade Glacier dominates the northern reaches of this landscape, its massive ice field giving way to the sprawling Blockade Lake. The map illustrates a glacial-fed drainage system where the North Fork Big River and South Fork Big River converge into the main channel of the Big River. This mid-century survey reveals an area defined by extreme elevation and ice, with numerous crevasses noted across the high peaks and glaciers. Human presence is almost non-existent in this portion of the Kenai Peninsula, marked only by a solitary Cabin near the Big River Lakes. These lakes form a complex network of water bodies at the river's base, where the braided streams slow and pool before continuing their course. The topography, reaching its height at Black Peak, provides a clear view of the natural barriers that have historically dictated travel and activity in this Alaskan interior.
