1952 Map of Holy Cross D-5

About this map

The Chuilnuk River meanders through the western reaches of this interior Alaskan landscape, while the Bonasila River cuts through the southeastern corner. This mid-century survey by the Army Map Service reveals a remote terrain defined almost entirely by its drainage systems and varying elevations. The watercourses, including the north-flowing Jackson Creek, provide the primary structure for understanding the geography before significant modern development. Photogrammetric methods from aerial photography taken in the early 1950s allowed for the detailed recording of these remote watersheds, offering a baseline for environmental historians studying the untouched river valleys of the Kusilvak region.
