1956 Map of Charley River A-4

About this map

The Charley River meanders through this interior Alaskan wilderness, serving as the central drainage for a complex network of tributaries such as Cultas Creek and Silvia Creek. Surveyed in the mid-1950s, the terrain is characterized by high ridges and deep valleys, evidenced by the numerous named watercourses that flow from the highlands toward the river basin. To the east, Fisher Creek and Derwent Creek drain the slopes near the unusual geological feature identified as a Pingo, a frost-heaved mound indicative of the region's permafrost environment. The southern portion of the map is defined by the steep rises of the Ogilvie Mountains, where Marks Creek and Highland Creek originate. This map documents a landscape before significant human development, highlighting the natural hydrological patterns of the Yukon-Charley region including Uncompahgre Creek and the remote Boston Gulch.
