1954 Map of Lime Hills A-7

About this map

Sparrevohn Air Force Station anchors the west side of this mid-century survey, reflecting Cold War-era defense priorities in the Alaskan interior. This installation is paired with a nearby Landing Strip, providing a rare point of human infrastructure in an otherwise remote landscape defined by complex hydrology. The drainage of Hook Creek and Caribou Snare Creek dominates the valley floors between significant peaks, including Cairn Mountain to the northeast. Mapped during the mid-1950s using photogrammetric methods from aerial photography, the sheet records the topography of the Lime Hills before significant modern shifts, capturing the precise layout of the early Air Force station and its relation to the surrounding unsurveyed land lines.
