1950 Map of San Clemente Island Central

About this map

Seal Cove marks the primary indentation along this central stretch of San Clemente Island, where the Pacific Ocean meets a landscape defined by sharp elevation changes and coastal promontories. Based on aerial photography and field checks performed during the war years, this survey illustrates a network of primitive roads and trails that traverse the high ridges, connecting points such as Black Point in the north to the southern reaches near Lost Point. The terrain is punctuated by significant landmarks including Arizona, Peak, and Boulder, with the coastal periphery defined by notable features like Eel Point and Mail Point. This 1950 edition captures the island's mid-century topography and basic infrastructure, showing a series of benchmarks and triangulation stations used by the Army Map Service to document this strategic offshore environment.
