1955 Map of Circle A-1

About this map

Military Reservation lands dominate the southwestern portion of this Alaskan interior landscape, where the Salcha River meanders through high-elevation terrain. This mid-century survey captures a watershed transition point where the South Fork Birch Creek and Yukon Fork flow north, while the Salcha drainage moves south toward the Tanana Valley. The map documents the vast, uninhabited stretches of the Fairbanks North Star Borough boundary before significant modern development reached this part of the interior. Tributaries like Caribou Creek, Williams Creek, and Puzzle Gulch define the intricate drainage patterns of the upland ridges. Localized features such as Big Windy Creek and Cottonwood Cr provide essential landmarks for understanding the hydrology and land use of this remote subarctic region during the 1950s.
