1949 Map of Big Delta C-6

About this map

The Tanana River and the sweeping infrastructure of the mid-20th century define this landscape in the Big Delta region. A large Military Reservation occupies the central and northern reaches, where the terrain is marked by remote drainage systems like Stuart Creek and Moose Creek. While the topography is based on 1949 surveys, purple revisions added in 1975 highlight the arrival of modern industry, most notably The Trans-Alaska Pipeline cutting across the southwestern corner. Transportation networks are concentrated near the river, following the Richardson Highway and Johnson Road. These corridors reveal the functional layout of the territory, including a Pumping Station and a Landing Strip, reflecting the shift from a landscape defined by natural waterways and survey markers like VABM Seven 2566 to one shaped by strategic energy and defense needs.
