1954 Map of Medfra C-3

About this map

Sulukna River meanders through this interior Alaska landscape, serving as a primary drainage for a series of named peaks and ridges during the mid-1950s. The topography is defined by prominent elevations such as Lone Indian Mountain in the northwest and the Von Frank Mountain massif to the south. The mapping reveals a complex network of waterways, including Browns Fork and Granite Creek, which flow through heavily contoured valleys between White Mountain and the southern Mystery Mountains. This survey, compiled from aerial photography, captures the drainage patterns of Whirlwind Ridge before any significant modern development altered the wilderness. The lack of permanent settlements or roads emphasizes the isolation of the Shepherd Creek and Johns Creek basins, where early explorers and surveyors relied on these natural landmarks for navigation in the Yukon-Koyukuk region.
