1954 Map of Lime Hills A-7

About this map

Sparrevohn Air Force Station defines the human footprint in this interior Alaskan landscape, serving as a remote military installation established during the early Cold War era. The topography is dominated by the prominent peak of Cairn Mountain, which overlooks a complex drainage system of high-altitude valleys and winding waterways. The presence of a Landing Strip adjacent to the station underscores the absolute reliance on aerial transport in this roadless region. Below the mountain ridges, Hook Creek and Caribou Snare Creek meander through the terrain, illustrating the natural watercourses that shaped the area long before the arrival of modern defense infrastructure. This 1954 data reflects a period when the United States was expanding its northern observation network through photogrammetric mapping and field annotations.
