About this map

Fort Greely dominates this interior Alaskan landscape, shown here as it transitioned into a permanent post during the early Cold War. The area is defined by its strategic military geography, anchored by the Big Delta Arctic Training Center and the Big Delta Airport. The braided channels of the Delta River flow north along the western boundary, while the Jarvis Creek drainage system weaves through the center, dotted with numerous small lakes such as Bolio Lake and Big Lake. Transport routes are clearly established, with the Richardson Highway running north-south and the junction of the Alaska Highway visible in the northeast corner. Notable landmarks for aviation and training include a CAA Station, a Rifle Range, and the prominent rise of Donnelly Dome to the south. This terrain illustrates the massive scale of military infrastructure required for arctic operations and territorial defense in the mid-20th century.
